Crystalline radical polymerizable composition for sealing electric and electronic parts, sealed body for electric and electronic parts using the composition, and method for producing the sealed body

摘要

PROBLEM TO BE SOLVED: To provide a crystalline radically polymerizable composition having excellent fluidity and good handleability.SOLUTION: The crystalline radically polymerizable composition for sealing an electric/electronic component according to the present invention, contains at least a crystalline radically polymerizable compound, an inorganic filler, a silane coupling agent, and a radical polymerization initiator. In a preferred embodiment of the crystalline radically polymerizable composition for sealing an electric/electronic component according to the present invention, the crystalline radically polymerizable compound contains one or more kinds selected from an unsaturated polyester, an epoxy (meth)acrylate, a urethane (meth)acrylate, a polyester (meth)acrylate, a polyether (meth)acrylate, a radically polymerizable monomer, and a radically polymerizable multimer.SELECTED DRAWING: None
