METHOD FOR PRODUCING STABILIZED POLYMER

Provided is a method of producing a stabilized polymer in which inhibition of polymerization of a monomer having an ethylenically unsaturated bond is suppressed even when a specific phenolic antioxidant is added before or during the polymerization of the monomer. The method of producing a stabilized...

More Information
Summary:Provided is a method of producing a stabilized polymer in which inhibition of polymerization of a monomer having an ethylenically unsaturated bond is suppressed even when a specific phenolic antioxidant is added before or during the polymerization of the monomer. The method of producing a stabilized polymer is characterized by comprising the step of adding at least one phenolic antioxidant which is represented by the following Formula (III) and masked with an organic aluminum to a catalyst system or a polymerization system before or during polymerization of a monomer having an ethylenically unsaturated bond:
