Title:
HOT-MELT ADHESIVE BASED ON BLEND OF AMORPHOUS AND CRYSTALLINE POLYMERS FOR MULTILAYER BONDING
Document Type and Number:
WIPO Patent Application WO2002053668
Kind Code:
A3
Abstract:
The present invention is generally directed to adhesive compositions comprising selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic. or isotactic configuration) is used to prepare adhesives of the present invention. As an example, a selected amount of isotactic polypropylene is blended with a selected amount of atactic polypropylene to prepare an adhesive composition having one or more performance properties (e.g., bond strength) that are superior to the perfomance properties of a conventional hot-melt adhesive.
