<p><P>PROBLEM TO BE SOLVED: To provide a method for making a hydrocarbon-based resin water-repellent, capable of forming a coat layer which is difficult to be peeled and has water repellency on a surface of the hydrocarbon-based resin, so as to make the hydrocarbon-based resin water-repellent. <P>SOLUTION: This method for making the hydrocarbon-based resin water-repellent comprises exposing the hydrocarbon-based resin to a mixed fluid which is formed by dissolving an acrylate ester or a methacrylate ester of formula (1): CH<SB>2</SB>=C(R<SP>1</SP>)-COO-R<SP>2</SP>(R<SP>1</SP>is H or methyl; and R<SP>2</SP>is a hydrocarbon group having F), an acrylate ester or a methacrylate ester of formula (2): CH<SB>2</SB>=C(R<SP>3</SP>)-COO-R<SP>4</SP>(R<SP>3</SP>is H or methyl; and R<SP>4</SP>is a hydrocarbon group not having F), and an initiator in CO<SB>2</SB>in a supercritical state or in a subcritical state and contains the components therein, and then decomposing the initiator by applying light and/or heat to a surface of the resin, so as to cover the hydrocarbon-based resin with a copolymerized polymer of the esters. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
