Isotactic polypropylene polymer is one, in which:
Isotactic polypropylene polymer is one, in which:
- A. all methyl groups are on one side of the extended chain. It is a highly crystalline, has high melting point and forms strong fibres
- B. the methyl groups present alternates regularly from one side to the other
- C. the methyl groups are distributed at random. It is a soft, elastic, and rubbery material
- D. None of these
Step-by-step solution
Isotactic polypropylene has all methyl groups on the same side of the polymer chain, leading to high crystallinity, high melting point, and strong fibers. Option B describes syndiotactic, C describes atactic, and D is incorrect.
