METHOD FOR JOINING NONPOLAR AND/OR LOW POLAR THERMOPLASTIC POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a joining method capable of joining a nonpolar and/or low polar thermoplastic polymer by thermal dielectric with micro waves and high-frequency waves not through a high polar thermoplastic polymer.;SOLUTION: A method for joining a nonpolar and/or low polar thermoplastic polymer includes: bonding a high polar liquid 6 which has a higher boiling point than that of the melting point of polymer bodies 4 and 5 to be bonded, to at least a portion to be joined to the other polymer body 5 (or another portion of polymer body) in one polymer body 4; bringing the one polymer body 4 and the other polymer body 5 (or another portion of polymer body) in contact with each other in the portion to be bonded; and then subjecting the liquid 6 to thermal dielectric thereby to thermally melt the portion to be bonded of the polymer bodies 4 and 5 through the liquid 6, and thereby joining the polymer bodies 4 and 5.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
