Polystyrene is a ______ polymer whereas dacron is a _____ polymer.
Options
- Astep growth, chain growth
- Bchain growth, step growth
- Ccondensation, addition
- Dthermoplastic, thermosetting
Correct answer
B. chain growth, step growth
Step-by-step solution
Polystyrene is an addition and chain growth polymer. It is thermoplastic. Addition polymers have unsaturated monomers. Dacron is a condensation and step-growth polymer. It is a fibre. Condensation polymerisation involves a repetitive condensation reaction between two bi-functional or tri-functional monomeric units.
