摘要:
The present invention is for a new class of allyl urethane resin which can be cured with peroxide at high temperature alone or in combination with some accelerators. These allyl urethane resins can be sued alone or in combination with other free radically polymerizable materials such as allyl monomers and ligomers or (meth)acrylate monomers and oligomers. These new allyl urethane resins contain at least two allyl functional groups.

The polymers are useful for coating and adhesive compositions prepared by radiation or peroxide curing processes.
摘要:
Composition suitable for free radical, radiation curable coating comprising at least one polyester having unsaturated backbone and at least one compound having two to six propenyl ether groups, and optionally, a free radical photoinitiator. The equivalent ratio of propenyl ether groups to maleimide, maleate and/or fumarate groups in the polyester is preferably about 5:1 to about 1:5.The process for curing the composition includes exposing it to ionizing radiation and/or ultraviolet light. The resultant cured coatings and coated articles are similar in performance to their vinyl ether analogues, but the propenyl ethers are easier to prepare than the vinyl ether analogues.
