Title:
LAMINATE INCLUDING ETHYLENE/α-OLEFIN/NONCONJUGATED POLYENE COPOLYMER COMPOSITION, AND ETHYLENE/α-OLEFIN/NONCONJUGATED POLYENE COPOLYMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/176796
Kind Code:
A1
Abstract:
The present invention addresses the problem of obtaining an ethylene/α-olefin/nonconjugated polyene copolymer composition having excellent adhesive strength with an ethylene/vinyl acetate copolymer saponified substance layer. The present invention relates to a laminate formed by laminating: an ethylene/α-olefin/nonconjugated polyene copolymer (A); and a copolymer composition layer including at least one additive selected from (1)-(3) with respect to 100 parts by mass of said ethylene/α-olefin/nonconjugated polyene copolymer (A), and an ethylene/vinyl acetate copolymer saponified substance (B) layer.
(1) 1.7-20 parts by mass of a dicumyl peroxide, and 2-20 parts by mass of a metal oxide
(2) 20-120 parts by mass of a hydrophilic fumed silica
(3) 5-50 parts by mass of an ethylene/vinyl acetate copolymer (B)
