<P>PROBLEM TO BE SOLVED: To provide a polyoxyalkylene-based polymer that is easily produced and curable by active energy rays or heat, and a composition excellent in curability and containing the polyoxyalkylene-based polymer. <P>SOLUTION: The polyoxyalkylene-based polymer (A) has at least one substituent in the molecule represented by the following: -O-C(=O)-NH-R<SP POS="POST">1</SP>-O-C(=O)-C(R<SP POS="POST">2</SP>)=CH<SB POS="POST">2</SB>, and has a number-average molecular weight of 3,000 or more. In formula, R<SP POS="POST">1</SP>is a divalent organic group, and R<SP POS="POST">2</SP>is a hydrogen atom or a 1-20C substituted or unsubstituted hydrocarbon group. <P>COPYRIGHT: (C)2012,JPO&INPIT |
