Which of the following statements concerning the stereochemistry of polymerization is correct?
A)Polymers in the atactic configuration are more likely to be crystalline solids because regular packing of the polymer chains is easier.
B)Polymers in the isotactic configuration tend to be softer and more flexible than atactic polymers.
C)In general,radical polymerization leads primarily to branched polymers in the syndiotactic configuration.
D)The percentage of chains in the isotactic or syndiotactic configuration decreases as the polymerization temperature decreases.
E)none of the above

Question

Quizplus · Accepted Answer

The correct statements about the stereochemistry of polymerization are contrary to the options provided. A) Atactic polymers are usually amorphous due to their irregular structure, making regular packing difficult. B) Isotactic polymers, with their regular structure, are more likely to be crystalline and less flexible compared to atactic polymers. C) Radical polymerization typically leads to atactic polymers, not specifically to branched polymers in the syndiotactic configuration. D) The stereochemistry of polymers, such as isotactic or syndiotactic configurations, is not directly related to polymerization temperature in the simplistic way described.
