Title:
ADHESIVE FOR BONDING TO LOW SURFACE ENERGY SURFACES
Document Type and Number:
WIPO Patent Application WO2001057151
Kind Code:
A3
Abstract:
A novel polymodal asymmetric elastomeric block copolymer and a pressure sensitive adhesive, tape and adhesive backed article made therefrom, such as a polymer foam article having a substantially smooth surface prepared by melt-mixing a polymer composition and a plurality of microspheres, at least one of which is an expandable polymeric microsphere, under process conditions, including temperature and shear rate, selected to form an expandable extrudable composition; and extruding the composition through a die.
