摘要： It is an object of the present invention to provide a polymer composition including a polymer produced by cationic polymerization in which the composition does not liberate a chlorine component by heating, which prevent processing apparatus, driers, etc. from corroding, and which is odorless and safe. The object is achieved by a polymer composition obtained by adding a double salt containing magnesium and aluminum as metal atoms to a polymer containing chlorine atoms produced by polymerizing cationically polymerizable monomers with an initiator in the presence of a Lewis acid.
