Abstract

Official abstract text for this publication.

A method for producing a modified molded article which includes molding a fluororesin to provide a molded article and irradiating the molded article with radiation at an irradiation dose of lower than 100 kGy at 50° C. to 200° C. to provide a modified molded article.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for producing a modified molded article comprising: molding a fluororesin to provide a molded article; and irradiating the molded article with radiation at an irradiation dose of lower than 100 kGy at an irradiation temperature of 50° C. to 200° C. and that is also lower than the melting point of the fluororesin to provide a modified molded article. 2. The production method according to claim 1 , wherein the molded article has a thickness of 0.01 to 3.0 mm. 3. The production method according to claim 1 , wherein the molded article is a tube, a film, or a bottle. 4. The production method according to claim 1 , wherein the modified molded article has a specific gravity of 2.14 to 2.30. 5. The production method according to claim 1 , wherein the fluororesin is a melt-fabricable fluororesin. 6. The production method according to claim 1 , wherein the fluororesin is a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer. 7. The production method according to claim 1 , wherein the fluororesin contains 0 to 500 functional groups per 10 6 carbon atoms in the main chain. 8. A modified molded article which is obtainable by the production method according to claim 1 .
