  • Functionalized olefin interpolymers, compositions and articles prepared therefrom, and methods for making the same
    Patent number: 9902882
    Abstract: The invention provides compositions containing at least one functionalized polyolefin, and in particular, to compositions containing at least one functionalized ethylene interpolymer, which has a melt viscosity less than 50,000 cP at 350° F. (177° C.) and a molecular weight distribution (Mw/Mn) from about 1 to 5. The invention also provides adhesive formulations containing the same. The invention also relates to the preparation of the functionalized interpolymers, by reacting, for example, such an ethylene interpolymer with the following: a) at least one unsaturated compound, containing at least one heteroatom, and b) at least one initiator.
    Type: Grant
