TL;DR: In this article, the morphology of different styrene/butadiene (SB) block copolymers with triblock architectures was investigated using tapping mode scanning force microscopy (SFM).
Abstract: The morphology of different styrene/butadiene (SB) block copolymers with triblock architectures was investigated using tapping mode scanning force microscopy (SFM). Comparative analysis of the morphology of the samples at the polymer/substrate interface of solution-cast films and in bulk was performed. It was found that, besides the total phase volume ratio, the interfacial structure between the incompatible chains determines the phase morphology and mechanical properties of the investigated block copolymers. The asymmetric SBS triblock copolymer (φps( 74 vol%) forms, as expected, a cylindrical morphology with hexagonally packed polybutadiene (PB) cylinders in the polystyrene (PS) matrix. Depending on the interfacial structure, block configuration, and the hard/soft phase ratio, other triblock copolymers (φps( 74 vol% and 65 vol%) show lamellae and randomly distributed PS cylinders in a random styrene/butadiene copolymer S/B matrix, respectively. *Dedicated to Prof. Francisco J. Balta Calleja on the occas...

TL;DR: In this article, a water-based binder for use in a slurry for investment casting is described. Butler et al. used a mixture of a colloidal silica sol and at least one latex polymer.
Abstract: The invention relates to a water based binder for use in a slurry for investment casting. The binder includes a mixture of a colloidal silica sol and at least one latex polymer. The latex polymer is preferably an acrylic latex or a styrene butadiene polymer (or a combination of these) which reduces the processing time between dips during shell mold making for investment casting. The latex polymer further lowers a critical concentration point or gelation point of the colloidal silica sol. The binder may be used as a primary binder or a backup binder in the shell mold making process. To make the slurry, the binder is combined with at least one refractory powder, preferably a refractory powder selected from the group of: alumino-silicates, fused silica, quartz silica, alumina, zircon, and zirconia.

TL;DR: In this paper, the authors used ground pistachio shell as alternative filler in a model natural rubber/styrene-butadiene rubber-based conveyor belt compound, which was prepared using a laboratory two-roll mill.
Abstract: Bio-based polymers and fillers draw a significant interest. Focus of this work is to use ground pistachio shell as alternative filler in a model natural rubber/styrene–butadiene rubber-based conveyor belt compound. Compounds were prepared using a laboratory two-roll mill by partial replacing of carbon black with pistachio shell. Cure characteristics, mechanical, thermal, morphological, and abrasion properties of pistachio shell containing vulcanizates have been studied. Increasing pistachio shell loading causes lower cure extent and lower tensile strength. However, abrasion resistance is significantly improved by incorporation of pistachio shell. Benefits of using pistachio shell as filler may include producing low price, environmentally friendly, and high abrasion resistant vulcanizates when some loses in tensile properties can be tolerated.

TL;DR: In this paper, random copolymerizing styrene and butadiene in a hydrocarbon solvent in the presence of an organolithium initiator and a Lewis base and, if necessary, an anionic surface active agent containing --SO3 M or --OSO3 M (wherein M is Na, K, Rb or Cs).
Abstract: Styrene-butadiene random copolymers having an average vinyl content of at least 70%, a breadth of the distribution of vinyl contents of at least 20%, a Mooney viscosity (ML1+4, 100° C.) of 10 to 150, and a styrene content of about 3 to 30% by weight. They are prepared by copolymerizing styrene and butadiene in a hydrocarbon solvent in the presence of an organolithium initiator and a Lewis base and, if necessary, an anionic surface active agent containing --SO3 M or --OSO3 M (wherein M is Na, K, Rb or Cs) under temperature-raising conditions. They are rubber materials having low rolling resistance and high wet skid resistance.
