CROSSLINKABLE COMPOSITION CROSSLINKED PRODUCT AND PROCESS FOR PRODUCTION THEREOF MULTILAYER STRUCTURE CROSSLINKING AGENT AND COMPOUND AND PROCESS FOR PREPARATION THEREOF

摘要

It is another object of the present invention to provide a crosslinkable composition and crosslinking agent capable of forming a crosslinked product having excellent interlayer adhesiveness when it is made into a multilayered structure by suppressing bleeding out from the crosslinked product as a crosslinked product having excellent retort resistance do. In the present invention, the [A] SP value is 9.5 ( / cm3)^1/2Or more and 16.5 ( / cm3)^1/2Or less and a crosslinking agent having at least one polar group containing nitrogen and oxygen atoms constituting the [B] aromatic ring and at least two polymerizable groups. The difference between the SP value of the polymer [A] and the SP value of the crosslinking agent [B] is 2 ( / cm 3 & ^1/2( / cm 3 ),^1/2Or less. The decomposition temperature of the [B] crosslinking agent is preferably 240C or higher, and the melting point of the [B] crosslinking agent is preferably 220C or lower.
