Patent number: 6794459Abstract: The present invention relates to cyclic polymers and their use in photolithographic applications. The cyclic polymers contain a pendant acid labile functional group and a functional group containing a protected hydroxyl moiety. The polymers are post modified by deprotecting the pendant hydroxyl moiety and reacting the deprotected hydroxyl containing moiety with a coreactant. The post-functionalized polymers find application in chemically amplified photoresist compositions.Type: GrantFiled: August 21, 2002Date of Patent: September 21, 2004Assignees: Sumitomo Bakelite Co., Ltd., International Business Machines Corp.Inventors: Saikumar Jayaraman, George Martin Benedikt, Larry Funderburk Rhodes, Richard Vicari, Robert David Allen, Richard Anthony DiPietro, Ratnam Sooriyakumaran, Thomas Wallow

Patent number: 6197984Abstract: A method of preparing amorphous copolymers of ethylene and at least one norbornene (NB)-type comonomer is disclosed. These polymers may be random or alternating depending on the choice of catalyst and/or the relative ratio of the monomers used. This method comprises polymerizing said monomers in a diluent or in bulk in the presence of a neutral nickel catalyst which may be represented by the formula wherein Y may be a saturated or unsaturated hydrocarbyl chain, X may be oxygen or sulfur, E may be phosphorus, arsenic, antimony, oxygen or nitrogen, R and R′ independently each is hydrogen or a hydrocarbyl group, L is a ligand containing a heteroatom P, N or O or L and R together with L may form part of a chelating structure in which case L is an ethylenic double bond.Type: GrantFiled: May 6, 1999Date of Patent: March 6, 2001Assignees: The B.

Patent number: 5741869Abstract: Addition polymers derived from norbornene-functional monomers are terminated with an olefinic moiety derived from a chain transfer agent selected from a compound having a terminal olefinic double bond between adjacent carbon atoms, excluding styrenes, vinyl ethers, and conjugated dienes and at least one of said carbon atoms has two hydrogen atoms attached thereto. The addition polymers of this invention are prepared from a single or multicomponent catalyst system including a Group VIII metal ion source. The catalyst systems are unique in that they catalyze the insertion of the chain transfer agent exclusively at a terminal end of the polymer chain.Type: GrantFiled: June 7, 1995Date of Patent: April 21, 1998Assignee: The B.F. Goodrich CompanyInventors: Brian Leslie Goodall, George Martin Benedikt, Lester Howard McIntosh, III, Dennis Allen Barnes, Larry Funderburk Rhodes

Patent number: 5668234Abstract: Acrylate monomers such as methyl methacrylate, or other suitable monomers such as lactams, lactones, or acrylamides, are polymerized by reaction injection molding (RIM) utilizing a combination of organo group-4 catalysts, e.g., a neutral organo catalyst and a cationic organo catalyst. Preferably a Lewis acid is utilized which reacts with the neutral organo catalyst and forms in situ the cationic organo catalyst. Significant exotherms are rapidly generated and result in short cure times and typically in high conversions of at least 95 percent by weight of the monomer. The catalysts of the present invention give good control of tacticity and thus high Tg polymers such as syndiotactic methyl methacrylate can be produced.Type: GrantFiled: September 12, 1994Date of Patent: September 16, 1997Inventors: Larry Funderburk Rhodes, Brian Leslie Goodall, Scott Collins
