配向したアクリレ-トPSA、その製造法及び使用法
Document Type and Number:
Japanese Patent JP2007518855
Kind Code:
A
Abstract:
The invention relates to an oriented pressure-sensitive adhesive and to a process for preparing it. The pressure-sensitive adhesive comprises an acrylate-based UV-crosslinked polymer which is synthesized in a mass fraction of at least 50% from at least one acrylic monomer according to the general formula (I) in which R1 is hydrogen (H) or a methyl group (CH3) and R2 is hydrogen (H) or a branched or unbranched, saturated C1 to C30 hydrocarbon radical, which may optionally be substituted by a functional group, the pressure-sensitive adhesive, in the form of a film applied as a melt (hotmelt), having a preferential direction which is characterized in the free film by a shrinkback of at least 3% relative to an original stretching of the film in the preferential direction. The orientation is generated after polymerization by means of a suitable coating process and is subsequently "frozen in" by UV crosslinking. The pressure-sensitive adhesive is outstandingly suitable for use as an adhesive layer on single-sided or double-sided adhesive tapes.
