Abstract
A method of making a foam uses the following steps. A mixture is created having a polymerizable condensation polymer and a blowing agent. The polymerizable condensation polymer has hydroxy acid units and unsaturated di-functional units. The unsaturated di-functional units are unsaturated dicarboxylic acid units or unsaturated di-alcohol units. The mixture is expanded to create a froth. The polymerizable condensation polymer in the froth is reacted to create the foam.
