Abstract
PURPOSE: A modifier is added to a specific chlorinated polyvinyl chloride resin composition and the product is pelletized, thus making it possible to impregnate the pellets with an organic volatile foaming agent in a short time and inhibit the foaming agent from flying away, whereby the composition is stably and efficiently heat extruded and foamed.
CONSTITUTION: A chlorinated polyvinyl chloride resin composition of 60W 75wt% chlorine content, preferably of 500W1,000 average polymerization degree and 63W73wt% chlorine content is combined with a modifier such as chlorinated polyethylene, preferably by 5W30pts.wt. and they are pelletized. Then, the pellets is impregnated with an organic volatile foaming agent of 7.5W8.4 solubility parameter and 0W30°C boiling point such as trichlorofluoromethane, preferably by 20W40pts. and heat extruded and formed. The modifier is preferably a compound that accelerates the impregnation of the foaming agens so that the impregnation reaches the impregnation of the foaming agent so that the impregnation reaches more than 20pts.wt. after 4hr at 80°C and holds the impregnated foaming agent more than half the original amount after 20hr at 23°C.
