ABSTRACT:
Controlled foams of crystalline amorphous polymers include a second phase polymeric material having a transition temperature below that of the matrix polymeric material. The second phase material provides nucleating sites for the growth of gas formed cells which are limited in size by the particle size of the second phase polymeric material.
