Solution
-
Condensation polymerisation is described by all of the following: it usually involves two different monomers, it produces a polymer plus a small molecule, and the functional groups on the two different monomers react together.
-
A dioic acid is HOOC-CH2-COOH.
-
A diol is joined with a dioic acid in a condensation polymerisation reaction to form Polyester plus water.
-
The functional group of an ester is ‒COO.
-
In a condensation polymerisation reaction between nHO-□-OH and nHOOC-□-COOH, 2nH2O water molecules are formed.
-
Methanediol is HO-CH2-OH.
