Patent number: 8383731Abstract: 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 ?-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.Type: GrantFiled: February 24, 2009Date of Patent: February 26, 2013Assignee: Exxonmobil Chemical Patents Inc.Inventors: Kenneth Lewtas, Sudhin Datta, Charles Cozewith, Bruce A.

Patent number: 7067603Abstract: The invention relates to novel adhesive alpha-olefin inter-polymers which are largely amorphous and have a rheological behavior that makes them suitable for adhesive use, both without and with minimzed amounts of tackifying resins. Specifically, the invention poly-alpha olefin inter-polymer may be composed of A) from 60 to 94% of units derived from one alpha mono-olefin having from 3 to 6 carbon atoms and B) from 6 to 40 mol % of units derived from one or more other mono-olefins having from 4 to 10 carbon atoms and at least one carbon atom more than A); and C) optionally from 0 to 10 mol % of units derived from another copolymerizable unsaturated hydrocarbon, different from A) and B); the diad distribution of component A in the polymer as determined by 13C NMR as described herein showing a ratio of experimentally determined diad distribution over the calculated Bernoullian diad distribution of less than 1.Type: GrantFiled: May 7, 2003Date of Patent: June 27, 2006Assignee: ExxonMobil Chemical Patents Inc.Inventors: Anthony G.
