    Abstract: Unsaturated polyesters formed from the condensation reaction of unsaturated and saturated dibasic acids and dihydric alcohols, at least a portion of which is 3-methyl-1,5-pentanediol, exhibit unexpectedly advantageous physical properties when copolymerized with an ethylenically unsaturated monomer.
