Abstract
Structurally isomeric poly(alkyl ethylenes) with H and Y structures, polymeric bridging segments and a Y index of 2×10 to 8×10 (kJ/mole/degree), have decreased instability in the melt and more advantageous processing properties. The structurally isomeric poly(alkyl ethylenes) with H and Y structures are synthesized by an irradiating method, a melt reaction method or a solid phase reaction method by reacting poly(alkyl ethylenes) with 0.05 to 5% by weight of monofunctional, difunctional and polyfunctional monomers, optionally in the presence of peroxides. The structurally isomeric poly(alkyl ethylenes) are suitable for producing films, sheets, panels, coatings, pipes, hollow objects and foams.
