CROSS-LINKED PRODUCT AND PRODUCTION METHOD AND USE THEREFOR, AND ETHYLENE COPOLYMER

Document Type and Number:

WIPO Patent Application WO/2015/129414

Kind Code:

A1

Abstract:

[Solution] A cross-linked product production method according to the present invention includes: a step for melt-processing an ethylene copolymer (A) that satisfies all of conditions (1), (2), and (3) and that has a structural unit derived from ethylene and a structural unit derived from a C3-C20 α-olefin, or for melt-processing a resin composition that includes the ethylene copolymer (A); and a cross-linking step. (1) Vinyl group content per 1000 carbons as determined by 1H-NMR is 0.06-1. (2) MFR10/MFR2.16 is 8.5-50. (3). Density (d) is 850-920 kg/m3. [Effect] By means of the cross-linked product production method according to the present invention, a cross-linked product that has favorable moldability and excellent mechanical strength can be obtained. The method is also highly productive, can produce a foam product that is lightweight and has excellent mechanical strength, and can provide cross-linked molded products that have little variation in the dimensions of individual products.
