PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND PRESSURE-SENSITIVE ADHESIVE TAPE USING SAME

Title:

PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND PRESSURE-SENSITIVE ADHESIVE TAPE USING SAME

Document Type and Number:

WIPO Patent Application WO/2013/183600

Kind Code:

A1

Abstract:

A pressure-sensitive adhesive composition containing a butene-based polymer, said butene-based polymer consisting of a 1-butene homopolymer that satisfies conditions (1) and (2) given below and/or a 1-butene-propylene copolymer that satisfies conditions (1') and (2) given below, and a pressure-sensitive adhesive tape using said pressure-sensitive adhesive composition in a pressure-sensitive adhesive layer make it possible to provide a highly adhesive pressure-sensitive adhesive composition and a pressure-sensitive adhesive tape using same. (1) The meso pentad fraction (mmmm) is between 3 and 80 mol%, inclusive. (1') The meso dyad fraction (m) is between 30 and 95 mol%, inclusive. (2) The latent heat of fusion (ΔHd) is less than or equal to 40 J/g.
