ABSTRACT:
Plastic foam materials having a high degree of structural integrity, cell network uniformity and small cell size are obtained from (meth)acrylic acid and (meth)acrylonitrile by incorporating acrylamide as a comonomer additive within certain ranges of concentration. Incorporation of the latter together with conventional additives normally used in preparing foams from the principal monomers helps to avoid preliminary precipitation during the polymerization process, and the gradients in the polymer microstructure which frequently result and cause internal stresses and weaknesses in the ultimate product.
