摘要：
A photocurable gel suitable for articles such as printing plates, photoresists and the like is disclosed. The photocurable eel comprises (a) a polymer composition having isotactic polymethyl methacrylate moiety; and syndiotactic polymethyl methacrylate moiety; (b) a photopolymerizable ethylenically unsaturated compound; and (c) a photopolymerization initiator. The gel is solid at ambient temperature and is capable of undergoing reversible gel/sol transition by heating or cooling. Methods of preparing articles, as well as methods of fixing articles, which use the gel are also disclosed. Such methods include sealing or affixing component parts on an electronic circuit board.
