TL;DR: In this paper, the performance of a plasma surface modified silica filler in styrene-butadiene rubber (SBR) matrix has been analyzed and the conditions of plasma modification were optimized by taking secant modulus as a standard parameter and the occurrence of the modification has been confirmed by surface area determination and Fourier transform infrared spectroscopy.
Abstract: The performance of plasma surface modified silica filler in styrene-butadiene rubber (SBR) matrix has been analyzed. The conditions of plasma modification have been optimized by taking secant modulus as a standard parameter and the occurrence of the modification has been confirmed by surface area determination and Fourier transform infrared spectroscopy. The plasma-modified surface of silica has been found to be composed of carbon–carbon double bonds and carbon–hydrogen bonds. Silane treatment also has been carried out on silica filler surface for a comparative assessment of its influence in the curing behavior and filler–rubber interaction. The cure reactions of all the rubber compounds have been found to be proceeded according to first-order kinetics. A reduction in the cure reaction rate constant has been observed with the loading of unmodified and surface modified silica, emphasizing the cure deactivation of the matrix rubber by the silica filler. The filler dispersion, as revealed by scanning electron microscopy, has been found to be greatly improved by the plasma as well as silane treatment. The filler–rubber interaction has been found to be greatly improved by both surface treatments, but the best balance of mechanical properties has been observed with plasma surface modification only.

TL;DR: In this article, the compatibility and storage stability of styrene-butadiene-styrene copolymer (SBS) modified bitumens were studied using fluorescence microscopy and dynamic mechanical analysis.
Abstract: The compatibility and storage stability of styrene-butadiene-styrene copolymer (SBS) modified bitumens were studied using fluorescence microscopy and dynamic mechanical analysis. Chemical characteristics of base bitumens and SBS polymers were determined by means of thin layer and gel permeation chromatography, respectively. The results showed that the morphology and phase separation of the modified binders varied with the characteristics of bitumens and polymers and were influenced by polymer content. At a given polymer content, the modified binders produced from bitumens with a higher content of aromatics exhibited better compatibility and higher storage stability. An increase in asphaltenes was observed to adversely affect storage stability. When mixing a small amount of polymer with bitumen, the modified binder showed dispersed polymer particles. At relatively high polymer content, depending on the base bitumens used, a continuous SBS phase was observed. On the other hand, the storage stability of modified binders decreased with increasing SBS content. Compared with branched SBS polymer, linear SBS displayed a finer dispersion in modified binder, and consequently, a lower phase separation was observed during hot storage. The degree of SBS dispersion in bitumen influenced storage stability and the rheological properties of modified binders; however, no definite relationships among them could be established.

TL;DR: In this paper, the authors investigated the flammability of SBR nanocomposites, which were prepared by the technique of cocoagulating rubber latex and clay aqueous suspension, and showed that the maximum heat release rate (HRR) decreased from 1987 to 1442 kw/m2 with the introduction of nanoclay (20 phr).
Abstract: The flammability of montmorillonite (MMT)/SBR nanocomposites, prepared by the technique of cocoagulating rubber latex and clay aqueous suspension, was investigated. Flammability studies, performed on the cone calorimeter, showed that the maximum heat release rate (HRR) of SBR decreased from 1987 to 1442 kw/m2 with the introduction of nanoclay (20 phr). This nanocomposite had the lowest mass loss rate and the largest amount of char upon combustion compared with conventional SBR composites with the same clay loading and pure SBR. The permeability properties of MMT/SBR composites were also measured. It was deduced that the lowered permeability was responsible for the reduced mass loss rate and hence the lower HRR. Unfortunately, the oxygen index (OI) of the nanocomposites was not as high as expected. Combination of Mg(OH)2 and clay was effective for the improvement of both mechanical properties and OI. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 97: 844–849, 2005

TL;DR: In this article, a reusable and compostable coated paper stock comprising a substrate coated on at least one surface with a primer coat and a top coat both of which are water-based dispersions is described.
Abstract: Recyclable and compostable coated paper stock comprising a substrate coated on at least one surface with a primer coat and a top coat both of which are water based dispersions. The primer coat comprises a water based dispersion of a polymer selected from the group comprising acrylic polymers, acrylic copolymers, polyvinyl acetate, polyvinyl alcohol, poly-ethylene vinyl acetate, poly-ethylene vinyl chloride, styrene butadiene copolymers, polyvinylidiene chloride or starch. The top coat comprises a water based dispersion of a polymer selected from the group comprising acrylic polymers, acrylic copolymers, styrene butadiene copolymers or polyvinylidiene chloride. In another embodiment the top coat further includes a wax component comprising 15-90 wt. % of the polymer and 5-85 wt. % of the wax. The substrate is coated with a primer coat prior to the application of the top coat to seal the substrate surface. The top coat forms a film over the primer coat and imparts water and grease resistant properties to the coated paper stocks. The invention also includes processes for making and using the invented coated paper stocks.
