Polymer blends of polyethersulfone (PES) with an all aromatic liquid crystalline co-polyester (LCP) were investigated. In addition, PES oligomers with the reactive functions end groups (−ONa) were added as a third component to the above blends in o

The relation between morphological change, induced by copolymerized benzene rings or by kneading, and the dielectric strength of ethylene-styrene copolymer was studied. In unkneaded samples, the lamellar thickness decreases and the lattice constant a

A study on the radiation resistance of two types of ethylene-styrene copolymers, random and graft, is described. It is shown that the random copolymer is highly resistant to gamma -rays in the aspects of carbonyl group formation, gel formation, and e
