Ethylenically unsaturated cyclic ortho esters are prepared by the reaction of a hydroxy-substituted cyclic ortho ester such as 4-hydroxymethyl-2-methoxy-2-methyl-1,3-dioxolane with acryloyl chloride, methacryolyl choride, vinylbenzyl chloride or the like. They form polymers, especially EPDM graft copolymers, which are useful in the formation of copolymer-containing compositions with polyesters, polyamides and the like. The copolymer-containing compositions have excellent physical properties and may be employed to compatabilize blends of the same polymers.
