A hyperbranched polyol with long flexible chains on the molecule surface was synthesized and characterized. The effect of the hyperbranched polyol as flexibilizer and chain‐transfer agent on cationic UV curing was investigated. It was found the hyperbranched polyol could markedly improve the mechanical properties of cured film. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 77: 1353–1356, 2000
