[PROBLEMS] To provide a novel composition particularly useful as an adhesive, which avoids the use of toxic materials such as isocyanates without losing the desirable properties of low molecular weight materials. In the presence of a non-amine based catalyst, α, β- The unsaturated polycarboxylic acid ester is reacted with a compound having the following structural formula. (R is a polyester or polyester amide; Represents CH 3 , CH 2 CH 3 , CH 2 CH 2 CH 3 or It is. ) |
