Polymer Technology Pickout the wrong statement. Polymers made of more than one monomer is called copolymer or mixed polymer Vulcanised rubber is more elastic than natural rubber Polymers made of only one monomer is called homopolymer The intermoleculer forces in ther-mosplastic polymers are intermediate to that of elastomers & fibres Polymers made of more than one monomer is called copolymer or mixed polymer Vulcanised rubber is more elastic than natural rubber Polymers made of only one monomer is called homopolymer The intermoleculer forces in ther-mosplastic polymers are intermediate to that of elastomers & fibres ANSWER DOWNLOAD EXAMIANS APP
