Abstract
Acrylyl esters of polyester-polyether copolymers are produced by reacting a hydroxyl-terminated polylactone polyester with alkylene oxide and esterifying the resulting polyester-polyether copolymer with an unsaturated carboxylic acid such as acrylic acid or methacrylic acid. The resulting reactive esters are useful in ink, coating or adhesive formulations curable by thermal or radiation means.
