COPOLYMER POLYMERS Polymers are synthesized from a chemical reaction of polymerization or chaining of monomers. According to the conditions of temperature and pressure (and eventually catalysts) we can obtain linear, branched, cross-linked or hyperramified polymers COPOLYMERS are macromolecules formed by several repetitive units, that is, prepared from two or more monomers. There are 4 copolymers of industrial importance1 . Commonly known as EVA rubber is vinyl ethylene-acetate. It is the product that you use as a yoga rug or alphabet leras as a puzzle for children. 2 . the plastic acrylonitrile-butadiene-styrene (ABS), 3 . styrene-butadiene rubber (SBR), and 4 . nitrile rubber, styrene acrylonitrile, styrene-isoprene-styrene (SIS). The acronym corresponds to the English names.
