Disclosed is a modified acrylic coating composition cured with melamine characterized by improved impact resistance which comprises: An acrylic polyol dissolved in a suitable solvent to 40-90% solids; 2 to 50% by weight of said acrylic polyol substituted with a polytrimethylene carbonate polyol selected from a polytrimethylene carbonate diol, a polytrimethylene carbonate triol, or a higher functionality polytrimethylene carbonate polyol; a melamine crosslinking agent; optionally a catalyst; and optionally pigments and other additives commonly used in coatings. Also disclosed in a related embodiment is a melamine/urea formaldehyde polytrimethylene carbonate coating composition that is prepared without acrylic.

Disclosed is a process for the production of poly(trimethylene carbonate) which comprises reacting trimethylene carbonate, a catalyst, and an alcohol, preferably a polyhydric alcohol, under nitrogen at atmospheric pressure and a moderate temperature, in a stoichiometric ratio to give the desired molecular weight of poly(trimethylene carbonate) in the presence of a catalyst selected from the group consisting of a salt, preferably an acetate, of an element of Group IA or IIA of the Periodic Table. In an alternative embodiment, high molecular weight poly(trimethylene carbonate) is produced without the use of an initiator, using the same catalyst and longer reaction times.

In accordance with the foregoing, the present invention comprises a polyester epoxy resin powder coating exhibiting improved impact resistance and flexibility, without the loss of other key properties and where the 1,3-PDO modified polyester has lower melt viscosity than polyesters made with 100% neopentyl glycol, which is formed by reacting: a) A carboxyl functional polyester resin formed by reacting one or more aliphatic glycols and one or more polycarboxylic acids and/or anhydrides, wherein 5 to 90% (on a molar basis) of the aliphatic glycol is 1,3-propanediol, in the presence of an esterification catalyst and then endcapping the polyester with an endcapping agent to ensure that the polyester has carboxyl chain ends; and b) An epoxy resin crosslinking agent.

Disclosed is a new class of TPUs with improved properties, based on poly(1,3-propanediol carbonate) diol, using 10 to 55% hard segment concentration, and cured with a diisocyanate. The composition provides a broader range of mechanical and thermal properties for TPU formulations, including improvements in hardness, higher elasticity modulus, and improved softening temperature and coefficient of thermal expansion, in addition to improved clarity.

A method for producing trimethylene carbonate poly(trimethylene carbonate which comprises (a) introducing liquid poly(trimethylene carbonate) and an optional catalyst into a wiped film evaporator reactor under a vacuum about 15 kPa or less, said reactor having walls heated to at least about 230 C. and an internal condenser heated to a temperature above the boiling point of trimethylene carbonate, (b)spreading the poly(trimethylene carbonate) into a thin film and allowing it to flow down the interior surface of the heated walls, (c) depolymerizing the poly(trimethylene carbonate) to form trimethylene carbonate which is driven to the internal condenser and residue poly(trimethylene carbonate) which continues down the reactor, and (d) collecting the trimethylene carbonate in a cooled distillate receiver.
