A composition comprising a reaction product of a diisocyanate, a chain extension agent having at least difunctional reactivity with an isocyanate, and a material comprising a blend of i) a primary carbamate material having at least one functional group reactive with an isocyanate and at least one primary carbamate group or a group convertible to a primary carbamate group, and ii) a reaction product of the primary carbamate material with an extending agent, wherein at least one of i) the isocyanate groups of the diisocyanate have a different reactivity in relation to each other, and ii) at least two of the groups with reactivity with an isocyanate on the chain extension agent have a different reactivity in relation to each other.

Urethane polymers that reduce the effect of polylactone linkages

A polymeric material is produced by atomizing into droplets a composition containing addition-polymerizable material and reacting the addition polymerizable material in the droplets to produce the particulate product. The polymeric product may be, for example, a powder coating composition.

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 R, R, R, R, Rand Rmay 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 Ror Rgroup 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 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&#xb0; C. and 50&#xb0; 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.

Asymmetric diisocyanate monomers in urethane polymers and oligomers to reduce crystallinity

The present invention provides 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 of the invention can be prepared by reacting a liquid 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 olefin-based block copolymer of the invention can be used to prepare an adhesion promoter that provides excellent adhesion of subsequent coating layers to olefinic substrates like TPO and superior properties as compared to previously used adhesion promoters containing chlorinated polyolefins. Alternatively, the olefin-based copolymers of the invention can be used as an additive in a curable coating composition to provide excellent adhesion to olefinic substrates like TPO, even when used in very minor amounts compared to the amounts required for previously known agents.
