Answer 1

The polymer microstructure relies on upon the way particles are composed along the chain: monomers can collect in various isomers (association that can't be changed without breaking covalent bonds). diverse stereoisomers observed in polystyrene (PS).

The polymer microstructure and its physical properties firmly relies on upon the stereoregularity of the chain pendant gatherings. Atactic polystyrene, which is generally utilized economically, is altogether formless because of the arbitrary plan of the pendant phenyl bunches, while syndiotactic and isotactic polystyrene, having more standard structures, display crystallinity.

After polymerization, a solitary sub-atomic chain can embrace various compliances. The quantity of adaptations relies on upon three attributes:

1) the chain adaptability (a few chains are solid like piano wires, some others are adaptable like silk string),

2) the cooperations between monomers in the chains (appealing or terrible)

3) collaborations with the environment.

On the off chance that attractions between monomers are solid, the polymer is a thick questions (broken down globule), On the off chance that there is no cooperation between monomers, the chain compliance is an arbitrary walk.

In the event that attractions between monomers are awful, the adaptation is a self-keeping away from walk.

At last, if long range shocks, (for example, electrostatic) between monomers exist, the compliance is broadened,
