Patent number: 7271231Abstract: Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc.Type: GrantFiled: October 20, 2003Date of Patent: September 18, 2007Assignee: E. I. du Pont de Nemours and CompanyInventors: Maurice S. Brookhart, Lynda Kaye Johnson, Christopher Moore Killian

Patent number: 7087691Abstract: Embodiments in accordance with the present invention encompass photo-imageable compositions that include polymers of acrylate-type monomers and norbornene-type monomers. In some embodiments a catalyst system comprising a cationic or a neutral Pd(II) dimer component having the formula (Allyl)Pd(P(R21)3) or (L?)[(L)Pd(R)(X)]2, respectively is employed to effect polymerization. In other embodiments a free radical or living free radical catalyst is employed to effect polymerization. At least one of the acrylate-type monomers and norbornene-type monomers of the polymer embodiments of the present invention encompass an acid labile moiety. Some polymer embodiments of the present invention include more than one type of acrylate-type monomer and norbornene-type monomer. Embodiments of the present invention include forming a patterned layer on a substrate and some embodiments include transferring the patterned structure to a material layer first formed on the substrate.Type: GrantFiled: July 7, 2003Date of Patent: August 8, 2006Assignees: Promerus LLC, Penn State Research FoundationInventors: Larry F.
