摘要： An adhesive blend is described that can include a semi-crystalline copolymer of propylene and at least one comonomer selected from the group consisting of ethylene and at least one C4 to C20 &agr;-olefin, the copolymer having a weight average molecular weight (Mw) from about 15,000 to about 200,000; an melt index (MI) from about 7 dg/min to about 3000 dg/min as measured by ASTM D 1238(B), and a (Mw/Mn) of approximately 2. Various production processes are also described. Also described are adhesive compositions and methods for making adhesive compositions having polymers or polymer blends with melt flow rates (MFRs) equal to and above 250° dg/min. at 230° C. Certain specific embodiments of the invention involve the use of a free radical initiator, e.g., a peroxide.

摘要： Ethylene propylene copolymers, substantially free of diene, are described. The copolymers will have a uniform distribution of both tacticity and comonomer between copolymer chains. Further, the copolymers will exhibit a statistically insignificant intramolecular difference of tacticity. The copolymers are made in the presence of a metallocene catalyst.

摘要： This invention relates to a method of making polymer compositions, e.g. EPDM compositions, in a multistage reactor with monomers chosen from ethylene, C3-C8 alpha olefins, and a non conjugated diene. In particular, the invention relates to a process for improving diene conversion during the manufacture of the aforementioned polymer compositions by use of a multistage reactor and a metallocene catalyst system.
