TL;DR: In this article, the fringed micelle model for crystalline-amorphous organization has been supplemented by the discovery and elucidation of chain folding and the relationship of chain-folded lamellae to spherulitic structures.
Abstract: N RECENT YEARS substantial progress has been made in the understanding of the Istructures and dynamics of high polymers. Crystal structures and chemical composition are well known for most common polymers [1, 2] . The fringed micelle model for crystalline-amorphous organization has been supplemented by the discovery and elucidation of chain folding and the relationship of chain-folded lamellae to spherulitic structures [2, 3]. Relaxation phenomena have been related to molecular motions, and qualitative and semiquantitative interpretations of diverse relaxation experiments show gratifying consistency [4, 5]. In this paper I

TL;DR: In this article, a polymer concrete (PC) was synthesized by mixing styrenated polyester (SP) and marble wastes as fillers, and the suitability of the prepared PC to be used as polymer based building materials was studied.
Abstract: A polymer concrete (PC) was synthesized by mixing styrenated polyester (SP) and marble wastes as fillers. The unsaturated polyester (UP) used was prepared from the reaction of oligomers obtained from the depolymerization of polyethylene terephthalate (PET) soft drink bottles with maleic anhydride and adipic acid. The UP was then mixed with the styrene monomers at a ratio of 60 : 40% by weight to obtain the SP used for the synthesis of the PC. The aim of this work is to study the suitability of the prepared PC to be used as polymer based building materials. Using marble and PET soft drink bottle wastes for the preparation of the PC affects the environment positively, by avoiding the accumulation of these wastes. Saving the raw materials of polymer and fillers for other applications is another economical advantage of preparing the PC from the recycled PET and marble waste. Mechanical integrity of the PC was studied as blocks prepared under different experimental conditions. Chemical resistance and water absorption were also followed to evaluate the durability of the products obtained. In addition, the flammability of the SP and the PC prepared was also studied. Based on the data obtained, it could be concluded that the PC under consideration has good chemical resistance for 20% Na2CO3,

TL;DR: In this paper, the authors measured Rheological characteristics using Dynamic Shear Rheometry (DSR) for two asphalts (A and B, conventional AC-20 viscosity grades) from different crude sources modified with 5% SBR, 5.5% LDPE, 5% SB, and a crumb rubber (5%)/SBS (2%) mixture.
Abstract: Rheological characteristics were measured using DSR (Dynamic Shear Rheometry) for two asphalts (A and B, conventional AC-20 viscosity grades) from different crude sources modified with 5% SBR, 5.5% LDPE, 5% SB, and a crumb rubber (5%)/SBS (2%) mixture. Mastercurves were constructed from DSR frequency sweeps at temperatures ranging from -20 to 80°C. The mastercurves were constructed using the method of reduced variables, similar to the WLF equation, and described all binders well except for the A-LDPE binder. Polymer network formation is suggested in the B-SB binders based on the tendency of the tan δ mastercurve to exhibit a local minimum and the lack of observable phase separated polymer domains within the resolution of the fluorescence microscope. The morphology of the SBR polymer in the asphalt was observed to be dependent on the specific asphalt source. Initiation of polymer network formation is postulated for B-SBR based on the behavior of tan δ and the asphalt swollen phase separated polymer domains...
