COMPOSITION, MATERIAL, FILM AND MEMBER FOR HIGH- FREQUENCY WELDING

摘要

PROBLEM TO BE SOLVED: To provide a composition for high-frequency welding which generates heat when exposed to high-frequency waves and which can make various members or materials high-frequency-weldable by applying it to the surface of a substrate to be treated to thereby form a layer thereon or by incorporating it into the substrate. SOLUTION: This composition contains a homopolymer of (A) a polymerizable monomer having an SP value of 9 or lower or a copolymer of (A) a polymerizable monomer having an SP value of 9 or lower and (B) another polymerizable monomer and has a product of permittivity by dielectric loss of 0.01 or higher.
