Abstract:
1. A hot melt adhesive composition, comprising: a) at least one thermoplastic silane grafted poly-α-olefin (P) that is solid at 25° C.; and b) at least one reaction product (RP) of a polyisocyanate with an isocyanate reactive silane (S); wherein the polyisocyanate is selected from the group consisting of 2,4- and 2,6-toluoylendiisocyanate (TDI), 4,4′-, 2,4′- and 2,2′-diphenylmethandiisocyanate, 1,3- and 1,4-phenylendiisocvanate, naphthaline-1,5-diisocyanate (NDI), 3,3′-dimethyl-4,4′-diisocyanatodiphenyl (TODI), 1,6-hexamethylendiisocyanate (HDI), 2-methylpentamethylene-1,5-diisocvanate, 2,2,4- and 2,4,4-trimethyl-1,6-hexamethylendiisocyanate (TMDI), 1,12-dodecamethylendiisocvanate, cyclohexane-1,3- and cyclohexane-1,4-diisocyanate, 1-isocyanato-3,3,5-trimethyl-5-isocyanatomethyl-cyclohexane (=isophorone diisocyanate or IPDI), perhydro-2,4′- and -4,4′-diphenylmethane diisocyanate (HMDI), 1,4-diisocyanato-2,2,6-trimethylcyclohexane (TMCDI), m- and p-xylylendiisocyanate (m- and p-XDI), m-tetramethyl-1,3- and m-tetramethyl-1,4-xylylene diisocyanate, p-tetramethyl-1,3- and m-tetramethyl-1,4-xylylene diisocyanate (m- and p-TMXDI), isocyanurates thereof, biurets thereof, and mixtures thereof, wherein the isocyanate reactive silane (S) contains only one isocyanate reactive group, wherein the isocyanate reactive group is selected from the group consisting of a hydroxyl group, mercapto group and amino group, and wherein the reaction product has a molecular weight M
