Compositions comprising a reaction product of a) an asymmetrical, saturated polyisocyanate that is non-cyclic, non-aromatic, and has at least 3 carbon atoms in the polyisocyanate per isocyanate group, b) a material that is at least one 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 and an extending agent, and c) optionally, a chain extension agent that has at least difunctional reactivity with an isocyanate. Also, methods of making these compositions.

Asymmetric polyisocyanate monomers in urethane polymers and oligomers to reduce crystallinity

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.
