Abstract
Compositions comprising a blend of a polyarylate and a poly(methylenebenzoate) wherein said polyarylate is derived from a dihydric phenol and an aromatic dicarboxylic acid, said poly(methylenebenzoate) comprises poly(p-methylenebenzoate), poly(m-methylenebenzoate) and mixtures thereof. These compositions have improved processability relative to the polyarylate, have improved weatherability relative to the poly(methylenebenzoate) and are transparent.
