Crosslinking aid and practical application thereof
The present invention provides a crosslinking aid comprising triallyl isocyanurate (TAIC), which serves for obtaining an adhesive resin exhibiting excellent insulation properties while maintaining good transparency, adhesive properties, heat resistance and flexibility of conventional crosslinked ethylene-vinyl acetate copolymers. The crosslinking aid of the present invention comprises a urethane poly(meth)acrylate in combination with triallyl isocyanurate.
1. A heat-crosslinking resin composition comprising an ethylene copolymer, a crosslinking agent and a crosslinking aid comprising a urethane poly(meth)acrylate in combination with triallyl isocyanurate.
2. A radiation-crosslinking resin composition comprising an ethylene copolymer and a crosslinking aid comprising a urethane poly(meth)acrylate in combination with triallyl isocyanurate.
3. A sealing material comprising the heat-crosslinking resin composition as defined in claim 1 .
4. A sealing material comprising the radiation-crosslinking resin composition as defined in claim 2 .
5. The sealing material according to claim 3 , which is used for a solar cell.
6. An ethylene copolymer composition comprising an ethylene copolymer, urethane poly(meth)acrylate and triallyl isocyanurate.
7. A solar cell comprising the sealing material as defined in claim 5 .
