Abstract:
The invention is a method for increasing the molecular weight of and optionally providing branching in a polymer which has a first repeat unit, which comprises the residual of a condensation reaction of an aliphatic dicarboxylic acid and either a bisamide diol or a bis diamide diester, and a second repeat unit, which comprises the residual of a condensation reaction of a diol and an aliphatic dicarboxylic acid. The invention is also the branched polymer that can be made by such a method.
