WebMar 5, 2024 · Elastomers are rubbers or rubberlike elastic materials. Thermoplastic polymers are hard at room temperature, but on heating become soft and more or less fluid and can be molded. Thermosetting polymers can be molded at room temperature or above, but when heated more strongly become hard and infusible. These categories overlap … WebNov 19, 2024 · Such a polymerization reaction is called copolymerization. Copolymers are of different types and different processes of polymerization can be used to form copolymers. Examples include Butadiene styrene copolymer, nitrile rubber, styrene isoprene styrene etc. When two monomer species are involved the resultant copolymer is called a bipolymer.
