Title:
メタロセン触媒オレフィン−α−オレフィンコポリマーに基づくホットメルト接着剤
Document Type and Number:
Japanese Patent JP5709749
Kind Code:
B2
Abstract:
Melt adhesive containing 5 to 40 wt.-% of at least one ethylene-based copolymer and at least one C3 to C20-α-olefin obtained through metallocene-catalyzed polymerization, 10 to 65 wt.-% of at least one tackifying resin, 0 to 35 wt.-% of a plasticizer, 0.01 to 30 wt.-% additives and additional ingredients selected from stabilizers, adhesion promoters, fillers or pigments, waxes and/or other polymers, wherein the total should amount to 100%, characterized in that copolymer A is a block copolymer that exhibits a substantially even elastic behavior in the range of 0° C. to 25° C., measured as the ratio of the storage modulus E′ according to (E′0C−E′25C)/E′25C<1.5.
