  • Patent number: 6977309
    Abstract: Provided is a compound having one or more structures of the formula: wherein X is a primary carbamate group, Y is a hydroxy or halide group, n is an integer of 2 or more, n? is an integer of 1 or more, and R0, R1, R2, R3, R4 and R5 may be H or a group selected from alkyl groups, aliphatic groups, cycloaliphatic groups, aromatic groups and mixtures thereof, with the provisos that at least one R1 or R2 group is selected from the group consisting of aliphatic groups, cycloaliphatic groups, and aromatic groups, and in substantially all structures primary carbamate group X is attached to a carbon atom having a lower degree of substitution than a carbon atom to which functional group Y is attached. The invention provides a method of making the claimed compound.

  • Patent number: 6939916
    Abstract: The composition is an adhesion promoter that includes a chlorinated polyolefin and an olefin-based block copolymer that has an olefin block that is substantially saturated and at least one (poly)ester or (poly)ether block. The olefin-based block copolymer can be prepared by reacting an hydroxyl-functional, saturated or substantially saturated olefin polymer with a chain-extension reagent that is reactive with hydroxyl groups and will polymerize in a head-to-tail arrangement of monomer units. The composition provides excellent adhesion to olefinic substrates like TPO. A method of making the adhesion promoter composition includes forming the olefin-based block copolymer, providing the copolymer at temperatures between 85° C. and 50° C. and adding, with agitation, chlorinated polyolefin to the copolymer at these temperatures. A coating is formed by combining the adhesion promoter with desired film-forming polymers, crosslinkers and coating additives.
