The structure of polyester PTT that is composed by terephthalic acid and 1,3-propanediol should be determined. Concept Introduction: Polymers are macromolecules which are composed of a large number of small repeating units. These repeating units are known as monomers and the process of formation of polymers from monomer units is known as polymerization . On the basis of type of polymers, polymerization reaction can be two types; addition polymerization and condensation polymerization. The addition polymerization occurs between monomer units with unsaturated bonds between carbon atoms. For example; polymerization of alkene leads to formation of polyalkenes. Condensation polymerization occurs with those monomers which have some functional groups like −OH, -COOH, -NH 2 etc. These polymerizations occur with elimination of small molecules such as H 2 O, CO, and CO 2 etc.

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.

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. Draw the structure of PLA
