摘要: A hydrogenated styrenic block copolymer (HSBC) is disclosed comprising, prior to hydrogenation, a polymer block A of at least one vinyl aromatic monomer, a polymer block B of at least one conjugated diene, and a copolymer block C of at least one vinyl aromatic monomer and 1,3-butadiene monomer. The HSBC has a total vinyl aromatic content of 15 to 60 wt.% and an aromatic blockiness index of 20 to 80%. The viscoelastic properties of HSBC show a value of a tan δ peak height of 0.7 to 2, a tan δ peak temperature of -40 to 25°C, and a temperature width value (in °C) at half the tan δ peak height of 17 to 40. The HSBC provides improved mechanical properties and can be used in preparation of adhesives and protective films applications.

摘要: The invention concerns a hot melt adhesive composition comprising:
i) a first metallocene-catalyzed propylene-based copolymer;
ii) a second metallocene-catalyzed propylene-based copolymer;
iii) a polyolefin copolymer selected from the group consisting of:
iii-1) acid-grafted polyolefin copolymer;
iii-2) a copolymer based on olefins and unsaturated monomers containing acid groups or anhydride groups; and
iii-3) mixtures thereof;
iv) a tackifier;
v) optionally a third metallocene-catalyzed propylene-based copolymer; wherein each of the metallocene-catalyzed propylene-based copolymers i) and ii) comprises, independently of each other, from 1% to 20% by weight of ethylene units.
