Abstract
This composition includes:at least one out of(A1) the graft polymers resulting from the grafting of at least one grafting monomer such as maleic anhydride onto (a) impact or crystal styrene homopolymers and copolymers and/or (b) optionally hydrogenated styrene-diene elastomer block polymers, (b) not being the only polymer in the mixture of (A) and (B);(A2) at least one copolymer (b) mixed with at least one polymer (B1);(A3) graft polymers resulting from the cografting of at least one grafting monomer onto a mixture of at least one polymer (a) and of at least one of (c) ethylene-vinyl acetate copolymers, ethylene-alkyl (meth)acrylate copolymers, ethylene homopolymers, and ethylene-&agr;-olefin copolymers;(A4) graft polymers resulting from the cografting of at least one grafting monomer onto at least one polymer (a) to which at least one tackifying resin (d) has been added, these graft polymers being mixed with at least one polymer (B1); and optionallyat least one out of(B1) graft polymers resulting from the grafting of at least one grafting monomer onto a polymer (c); and(B2) (ethylene-&agr;-olefin or vinyl acetate or alkyl (meth)acrylate-monomer of the type of the above-mentioned g…
