Molecular formula : MW : CAS :
nature : a type of synthetic rubber. The chain is the main base or carboxyl terminal on the binary or ternary polymer. By unsaturated carboxylic acid (such as acrylic acid, etc.) and the butadiene and styrene, butadiene or acrylonitrile and other derived by emulsion polymerization, such as carboxylated styrene-butadiene rubber, carboxylated nitrile rubber. With great strength, thermal stability, high resistance tales, cold resistance, tear-resistant and anti Inflectional repeatedly have good performance advantages. Elongation smaller. Available sulfur vulcanization (rubber can retain good flexibility), use of metal oxides and hydroxides or two isocyanate such as sulfide (products can enhance the strength and prone to early sulfide), two normally use. Used in the manufacture of high-strength film-forming materials, adhesives and other rubber products.
