摘要:
A process for preparing a functionalized polymer composition and a functionalized polymer composition. The process comprises the steps of providing a hydrocarbon resin, a polyolefin and a graft monomer, and dispersing the hydrocarbon resin in the polyolefin, followed by adding the graft monomer under shear to prepare the functionalized polymer composition. The polyolefin can comprise a polyethylene polymer or a C3 to C40 polymer having a molecular weight (Mw) of at least 20000.

摘要:
The packaging industry desires adhesive compositions having a fast set time, such as those setting in less than five seconds from a molten state at conventional packaging operating temperatures to a solid or quasi solid having favorable Dot T-Peel, set time, and/or fiber tear adhesion properties. Polymer based adhesives performing within this window are a favorable alternative to conventional formulated adhesives. The provided adhesive compositions exhibit a favorable balance of properties such as high adhesive strength, wide temperature operating window, and fast set time. Provided are adhesive compositions composed of a polyolefin composition comprising at least about 50 mol % polypropylene, at least one wax and at least one wax modifier.
