What modification occurs when a small amount of p-divinylbenzene is added to the polymerization reaction of styrene to form polystyrene? (Recall that the vinyl group is -CH=CH₂.) A)Cross-linking of the polystyrene B)Isotactic stereochemistry of the polystyrene C)Syndiotactic stereochemistry of the polystyrene D)"Softening" of the polystyrene by a plasticizer

Question

Quizplus · Accepted Answer

The addition of p-divinylbenzene to the polymerization reaction of styrene results in cross-linking of the polystyrene, as the divinylbenzene molecules can react with the styrene molecules to form bonds between them. This leads to a more rigid and durable material.
