PROBLEM TO BE SOLVED: To obtain a polyurethane foam having high mechanical strengths by using an active hydrogen component containing a specified polymer polyol and simultaneously performing the polymerization of the addition-polymerizable functional groups and the reaction of forming a polyurethane. SOLUTION: This foam is prepared by using an active hydrogen component comprising an addition-polymerizable active hydrogen component (A) and a polymer (B) dispersed therein. In the active hydrogen component, component A comprises a compound having an active hydrogen containing group and an addition-polymerizable functional group or a compound having an active hydrogen containing group and having no addition-polymerizable functional group, and component B is a polymer polyol comprising a polymer of an addition polymerizable functional group containing compound having no active hydrogen containing group and/or component A comprises a compound having an active hydrogen containing group and having no addition-polymerizable functional group and a compound having an addition-polymerizable functional group and having no active hydrogen containing group, and component B is a polymer polyol comprising a polymer of a compound having an addition-polymerizable functional group and having no active hydrogen containing group and having a content of the compound having an addition-polymerizable functional group and having no active hydrogen-containing group of 1-80 mass %. |
