Title:

METHOD OF IMPARTING FUNCTION TO MOLDED POLYMER AND APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/2008/069041

Kind Code:

A1

Abstract:

A method of imparting a highly durable function to a polymer molding. By the method, various function-imparting agents can be efficiently imparted to a polymer molding. In the method, the amount of a waste liquid resulting from the processing can be reduced as much as possible. The waste liquid and function-imparting agents can be recovered and can be reused according to need. The function-imparting agents can be imparted to a polymer molding not batchwise but continuously. Also provided is an apparatus for the method. The method of imparting a function to a polymer molding comprises ejecting a supercritical fluid to a polymer molding to tenaciously bond a function-imparting agent to the polymer molding.
