A polyesteracetal contains —[C(O)(CR 3 R 4 ) x (C(O)) y OCR 1 R 2 O]— repeating unit where x is 0 to 5, y is 0 or 1, and R 1 , R 2 , R 3 and R 4 are independently H, C 1 to C 24 alkyl, C 2 to C 24 alkenyl, C 6 to C 14 aryl, C 7 to C 24 alkylaryl, heteroatom interrupted C 1 to C 24 alkyl, heteroatom interrupted C 2 to C 24 alkenyl, heteroatom interrupted C 4 to C 14 aryl, or heteroatom interrupted C 5 to C 24 alkylaryl, and wherein on average x>1 or y>0. The polyesteracetal can be a homopolymer or copolymer. A method of preparing the polyesteracetal comprises a ring-opening polymerization of a cyclic esteracetal monomer using a metal alkolate, metal alkoxide or metal alkyl initiator. |
