Patent number: 6965000Abstract: The present invention is directed to a method for producing a copolymer and a copolymer product of the method. The copolymer is prepared by a controlled radical polymerization process, typically an atom transfer radical polymerization process, in which polymerizable alkene monomers are polymerized in the presence of a halogenated polyolefin macroinitiator. The copolymer product of this process is useful in a film-forming composition that adheres strongly to polyolefinic substrates and to which non-polyolefinic film-forming compositions strongly adhere. The copolymer can be applied to a substrate in an adhesion-promoting layer or can be incorporated into a film-forming composition, such as a primer, that contains additional resinous compounds.Type: GrantFiled: June 10, 2004Date of Patent: November 15, 2005Assignee: PPG Industries Ohio, Inc.Inventors: Simion Coca, Brian K.

Patent number: 6900279Abstract: A composition that includes a non-gelled copolymer that includes one or more residues of a first polymerizable ethylenically unsaturated monomer containing a pendant amide, ester or carboxylic acid group. The nearest neighboring monomer residues of the majority of the first monomer residues along the copolymer molecule do not contain pendant carbonyl functional groups. The amide, ester or carboxylic acid group of the residues of the first monomer are the post polymerization transesterification, transamidification or hydrolysis reaction product of a C1-C4 alkyl ester group in the unreacted first monomer with a compound selected from amine functional compounds and hydroxy functional compounds. The reacted copolymer is substantially free of cyclical structures resulting from the transesterification, transamidification or hydrolysis reaction. The compositions may be thermosetting compositions useful in multi-layer composite coatings.Type: GrantFiled: January 21, 2003Date of Patent: May 31, 2005Assignee: PPG Industries ohio, Inc.Inventors: Simion Coca, Gregory J.
