Abstract
PURPOSE: A composition useful to remove and wash the resin or its carbonized product left attached whithin a molding machine after extrusion or injection molding of a thermoplastic resin, prepared by adding an α-olefin epoxide to a cellulose acetate resin.
CONSTITUTION: The titled composition is obtained by adding 0.1W20pts.wt. α- olefin epoxide of the formula, wherein R is H or a linear saturated alkyl, provided that total number of carbons of R and R' is 8W42, to 100pts.wt. cellulose acetate resin, e.g., cellulose diacetate or cellulose acetate propionate, and melt- mixing the resulting mixture. The above composition is used to wash a molding machine in molding a variety of thermosetting resins, for example, in case where the resin remaining around screws is carbonized by thermal degradation, the type of resin is changed, or a different color resin is molded.
EFFECT: Washing is possible with a small quantity of the composition.
