Abstract
A heterogeneous blend of elastomers having a stabilized morphology, as well as the method of making the same, comprises at least two radiation cross-linkable elastomers which form a heterogeneous blend. The radiation cross-linkable elastomer components are selected from the class consisting of conjugated dienes having from 4 to 12 carbon atoms, natural rubber, polyalkenamers such as polypentenamer, chlorinated polyolefinic elastomers having from 2 to 8 carbon atoms such as chlorinated polyethylene, ethylenepropylene terpolymers, polysiloxanes, nitrile rubber, butadiene-acrylic copolymers, chlorosulfonated polyethylene, butadiene vinyl pyridine copolymers, substituted phosphazenes, aliphatic polyesters which are substantially non-crystalline and have 6 carbon atoms or more in the repeating unit, preferably from 6 to 12 carbon atoms, butyl copolymers containing groups with unsaturation, a butadiene-styrene copolymer and a copolymer, terpolymer, etc., made from a conjugated diene having from 4 to 12 carbon atoms and from monomers selected from the class consisting of a vinyl aromatic having from 8 to 15 carbon atoms, acrylonitrile, and olefins having from 2 to 8 carbon atoms. The morp…
