Abstract:
A composite made by the process comprising melt mixing(a) a polymer comprising a polyester having at least one isocyanate reactive groups comprising the reaction product between (1) a first glycol component comprising an aliphatic glycol, a cycloaliphatic glycol, an aromatic glycol, or a combination thereof, and (2) a first dicarbonyl component comprising an aliphatic dicarbonyl compound, a cycloaliphatic dicarbonyl compound, an aromatic dicarbonyl compound, or a combination thereof, wherein the first dicarbonyl component further comprises a third dicarbonyl compound, wherein the third dicarbonyl compound comprises trimellitic acid, trimellitic anhydride, pyromellitic dianhydride, or a combination thereof, wherein the polymer is from 30 to 90% by weight of the composite;(b) a thermoplastic polyurethane at from 0.1 to less than 10% by weight of the composite; and(c) a reinforcing fiber at from 9.9 to 60% by weight of the composite, wherein the sum of the weight percentages of components (a)-(c) is equal to 100%.
