What type of polypropylene has all methyl groups arranged on the same side of the polymer chain?
Understand the Problem
The question is asking about the classification of polypropylene based on the spatial arrangement of its methyl groups along the polymer chain. It specifically focuses on identifying which type of polypropylene has all methyl groups on the same side.
Answer
Isotactic polypropylene.
The polymer type with all methyl groups arranged on the same side of the chain is isotactic polypropylene.
Answer for screen readers
The polymer type with all methyl groups arranged on the same side of the chain is isotactic polypropylene.
More Information
Isotactic polypropylene has a highly crystalline structure due to the orderly arrangement of the methyl groups, which affects its physical properties such as melting point and mechanical strength.
Tips
A common mistake is confusing isotactic with atactic or syndiotactic polypropylene. Isotactic has all methyl groups on the same side, while atactic has a random arrangement, and syndiotactic has alternating sides.
