Question

(a) Draw a correct wedge and dash rendition of the repeat unit of polyisobutylene

(b) Determine the molecular weight of the repeat unit

(d) Determine the number of formula units present in the crystalline unit cell

(e) If the number average molecular weight is 150000 , find the degree of polymerization

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.
