Abstract

PURPOSE: To obtain a sound absorbing material having improved heat and water resistance and porosity and air-permeability, by adding benzoyl peroxide to glycidyl methacrylate, adding diluents thereto, polymerizing the resultant mixture in a suspention state, and incorporating a binder and a curing agent with the resultant suspended polymer.
CONSTITUTION: 1wt% Benzoyl peroxide is added to glycidyl methacrylate, and 50W150vol%, based on the monomer, isooctane, petroleum benzine and ligroin are added as diluents to carry out the suspension polymerization. Furthermore, a binder and a curing agent are added to the polymer, and the resultant mixture is then molded and dried. For example, 100pts.wt. polymer is mixed with 20pts.wt. unsaturated polyester as a binder and 2W3wt%, based on the binder, Kayamek as a curing agent to give the most suitable composition.
