a) Syndiotactic polyacrylonitrile Interpretation: Draw the three-dimensional structure of the polymeric products given in the question. Concept introduction: Isotactic, syndiotactic, and atactic are the stereochemical forms. The polymer having the (-R) group on the same side of the macromolecule backbone (zig-zag bone) is known as isotactic polymer. An isotactic macromolecule consists of 100% meso diads. Syndiotactic are the macromolecules in which the (-R) groups are arranged in an alternate manner along the long chain of the polymer. Gutta percha is also an example for Syndiotactic polymer. In atactic form, the substituents are placed in a random manner along the long chain. The important point to note here is that the polymer obtained from the chain growth polymerization mechanism must have chiral carbons to possess these structures. If the polymer formed does not have chiral carbon then it cannot occur in isotactic, syndiotactic and atactic forms.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
