The polyester sheet in accordance with an aspect of the present invention contains crystals of polyester which is a polycondensate of polyvalent carboxylic acid and polyalcohol. The polyester sheet contains nano-oriented crystals which contain crystals of polyester in each of which a polymer chain is highly oriented and each of which has a crystal size of 50 nm or less. A heatproof temperature of the polyester sheet is higher than a temperature that is lower than an equilibrium melting point of the polyester by 80° C., and a melting point of the polyester sheet is higher than a temperature that is lower than the equilibrium melting point of the polyester by 40° C.

The present invention provides a polyester which is the reaction product of reactants comprising: (A) an aliphatic dicarboxylic acid comprising from 16 to 30 carbon atoms; (B) an aromatic carboxylic acid and/or anhydride; and (C) a polyol. The invention also provides a coating composition comprising the polyester, a method of making the coating composition and the use of at least 2 wt % of a linear aliphatic dicarboxylic acid comprising from 16 to 30 carbon atoms as a replacement for at least 2 wt % of an aromatic carboxylic acid and/or anhydride in a polyester composition. This use may improve the UV resistance and/or stability of the polyester composition.

A filler material of a thermoset resin of a diacid/polyol, such as PGS is provided. The filler useful in forming composites, such as those in which the filler and a resin matrix are of the same material to provide a homogenous polymeric composition.
