Fusible adhesive based on alpha-olefin copolymers metallocene catalyzed

摘要

Fusible adhesive containing: a) from 5 to 40% by weight of at least one ethylene-based copolymer and at least one α-olefin of C3 to C20, obtainable by polymerization catalyzed with a metallocene, b) 10 65% by weight of at least one tackifying resin, c) 0 to 35% by weight of a plasticizer, d) 0.01 to 30 wt% selected from stabilizers, tackifiers, fillers, pigments additives , waxes and / or other polymers, the sum of the percentages should equal 100%, wherein the copolymer is a block copolymer, having an elastic behavior largely linear in the range of 0 to 25, measured as the ratio accumulation module E 'according to equation (E'0ºC-E'25ºC) / E'25ºC 1.5.
