WebENGINEERING PROPERTIES OF POLYETHYLENE 3 weight will have a comparatively high melt index. Conversely, resins with a relatively high molecular weight will yield a lower melt index. From this relationship, we can associate changes in physical properties (as shown in Table 1-1) with changes in melt index of the material. Web3.1. Synthesis of poly(p-phenyl styrene-sulfonate) PSS by ATRP. PSS was prepared by the ATRP of SS, as illustrated in Scheme 1. The effects of ligand and solvent on the polymer yield and the polydispersity were summarized in Table 1. The ATRP conditions for SS were set as same as S polymerization [Citation 59]. WebPolycarbonate. Polycarbonates ( PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many ... fnaf ultra custom night free play
