Abstract:
A radiation-crosslinkable composition comprising:(a) an elastomeric polymer containing abstractable hydrogen atoms in an amount sufficient to enable the elastomeric polymer to undergo crosslinking in the presence of a suitable radiation activatable crosslinking agent; and (b) a radiation-activatable crosslinking agent of the formula: wherein:X represents CH3â€”; phenyl; or substituted-phenyl, or substituted-phenyl with the proviso that any substituents on the substituted-phenyl do not interfere with the light-absorbing capacity of the radiation-activatable crosslinking agent and do not promote intramolecular hydrogen abstraction of the radiation activatable crosslinking agent; W represents â€”Oâ€”, â€”NHâ€”, or â€”Sâ€”; Z represents an organic spacer selected from the group consisting of aliphatic, aromatic, aralkyl, heteroaromatic, and cycloaliphatic groups free of esters, amides, ketones, urethanes, and also free of ethers, thiols, allylic groups, and benzylic groups with hydrogen atoms intramolecularly accessible to the carbonyl group of said radiation-activatable crosslinking agent; and n represents an integer of 2 or greater.
