The reason as to why styrene ( CH 2 = CHPh ) can be polymerized to polystyrene by all three methods of chain-growth polymerization is to be explained. Concept introduction: The simpler units which combine to form polymers are known as monomers. The process by which respective monomers combine to form polymers is known as polymerization. Chain-growth polymerization is formed by the repetitive addition of monomer units containing double or triple bonds. If the monomer units undergoing addition are the same, the polymer is known as homopolymer .

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.

Explain why styrene (CH2=CHPh) can be polymerized to polystyrene by all three methods of chain-growth polymerization.

Poly(lactic acid) (PLA) has received much recent attention because the lactic acid monomer [CH3CH(OH)COOH] from which it is made can be obtained from carbohydrates rather than petroleum. This makes PLA a more “environmentally friendly” polyester. (A further discussion of green polymer synthesis is presented in Chapter 28.) Draw the structure of PLA.
