Abstract: 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.

Abstract: Copolymerizable benzophenone photoinitiators of the formula I ##STR1## wherein 1, k=0, 1, 2.R.sub.1 =divalent organic group having 1 to 25 carbon atoms;R.sub.2 =H or methyl; andR.sub.3, R.sub.4 =organic group having 1 to 25 carbon atoms.X, Y=hydrogen, halogen or (C.sub.1 -C.sub.25) groups containing N, S, and/or O;and method of making the photoinitiators.The photoinitiators overcome the leaching problem with prior photoinitiators in radiation curable polymer applications. Radiation curable polymers, cured polymers, and coated articles are also disclosed.

Abstract: A process for epoxidizing unsaturated polymers comprising reacting an unsaturated polymer with hydrogen peroxide in the presence of (a) tungstic acid or its metal salts, (b) phosphoric acid or its metal salts, and (c) at least one phase transfer catalyst.
