    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.

    摘要： An activator for olefin polymerization catalysts is disclosed. One aspect of the activator is that it comprises a group-13 central atom connected to at least one fluorinated aryl ring that is itself substituted with a silyl acetylenic group. Some embodiments employ a neutral activator and others employ the activator as an anion coupled with a ligand-abstracting cation. These activators are discrete molecules.
