The invention relates compositions containing at least one silane-grafted polyolefin, and in particular, to compositions containing at least one silane-grafted ethylene/α-olefin polymer, which has a melt viscosity less than 50,000 cP, and adhesives containing the same. In one embodiment, the at least one silane-grafted ethylene/α-olefin polymer is formed from an ethylene/α-olefin polymer that has a molecular weight distribution from 1 to 3.5. The invention also relates to the preparation of the silane-grafted polymers, by reacting, for example, an ethylene/α-olefin polymer with at least one silane compound and at least one initiator.
