Patent ID: 10196534

Abstract:
A resin composition for sealing an electronic device and other things being capable of suppressing the permeation of water vapor is provided. The present invention includes a polybutadiene polymer represented by chemical formula (1) and having a (meth)acryloyl group at a terminal end; and a photopolymerization initiator, and does not include a thermoplastic resin having a mass-average molecular weight of 50,000 or more: wherein R1 and R2 each represent a hydroxyl group or H2C═C(R7)—COO—; R3 and R4 each represent a C1-C16 substituted or unsubstituted divalent organic group; R5, R6 and R7 each represent a hydrogen atom or a C1-C10 alkyl group, and at least one organic group represented by chemical formula (2) is included within chemical formula (1); l and m each represent 0 or 1; n represents an integer of 15-150; and x:y=0 to 100:100 to 0; R1 and R2 are never both a hydroxyl group.
