Abstract: Take the pentaerythritol as "the central core", cause it to react with 1,2,4-benzenetri-carboxylic anhydride and the epichlorohydrine and synthesize the extra branched alkali soluble polyester. Use the peripheral carboxyl group of synthetic polymer molecules to react with the gly-cidyl methacrylate, and introduce the reactive methacryloyl oxygen radical to the molecule periphery of extra branched polymer. This study has explored the effect of resin composition on photosensitiv-eness and alkali solubility. The result indicates that, through the adjustment of the peripheral carboxyl group and the reactive methacryloyl oxygen radical content, a good alkali solubility and pho-tocuring may be obtained.

Key words: hyperbranched polymers, photocuring, alkali solubility
