Polymer Technology In step growth polymerisation, condensation occurs in a stepwise manner with or without the elimination of smaller molecules. An example of step growth polymerisation product is Terylene PVC Polypropylene Polybutadiene Terylene PVC Polypropylene Polybutadiene ANSWER DOWNLOAD EXAMIANS APP
Polymer Technology Pickout the wrong statement. The intermoleculer forces in ther-mosplastic polymers are intermediate to that of elastomers & fibres Polymers made of only one monomer is called homopolymer Polymers made of more than one monomer is called copolymer or mixed polymer Vulcanised rubber is more elastic than natural rubber The intermoleculer forces in ther-mosplastic polymers are intermediate to that of elastomers & fibres Polymers made of only one monomer is called homopolymer Polymers made of more than one monomer is called copolymer or mixed polymer Vulcanised rubber is more elastic than natural rubber ANSWER DOWNLOAD EXAMIANS APP
