Patent number: 6806331Abstract: A catalyst for bulk polymerization of a polymerizable unsaturated compound comprises a compound having at least one thiol group and a secondary hydroxyl group and represented by the following formula (I): wherein R1 to R5 are each a hydrogen atom or an alkyl group, and R6 is a hydroxyl group, an alkyl group or the like. Also a process for bulk polymerization of the invention comprises polymerizing a polymerizable unsaturated compound in an inert gas atmosphere substantially in the absence of a solvent using, as a catalyst, a compound having at least one thiol group and a secondary hydroxyl group and represented by the above formula (I). According to the catalyst or the process, bulk polymerization can be carried out in one-component catalyst system in a high yield without suffering a runaway reaction.Type: GrantFiled: April 20, 2000Date of Patent: October 19, 2004Assignee: Soken Chemical and Engineering Co., Ltd.Inventors: Syuji Okamoto, Hiroshi Ueno
