Patent ID: 6855799

Claim:
A polymeric composition comprising repeat units derived from (1) phosphorus trichloride, (2) an aromatic polyhydric alcohol wherein the location of the OH groups thereof are placed such that, when the polyhydric alcohol is contacted with PCl 3 , monodentate phosphites are not predominately produced, and (3) an aromatic diol that has a formula selected from the group consisting of and combinations of two or more thereof; each R 4 is independently selected from the group consisting of hydrogen, C 1 to C 12 alkyl or cycloalkyl group, acetal, ketal, —OR 3 , —CO 2 R 3 , C 6 to C 20 aryl group, —SiR 3 , —NO 2 , —SO 3 R 3 , —S(O)R 3 , —S(O) 2 R 3 , —CHO, —C(O)R 9 , —F, —Cl, —CN, —CF 3 , —C(O)N(R 3 )(R 3 ), —A 1 Z, and combinations of two or more thereof; A 1 is a C 1 to C 12 alkylene group: Z is selected from the group consisting of —CO 2 R 3 , —CHO, —C(O)R 3 , —C(O)SR 3 , —SR 3 , —C(O)NR 1 R 1 , —OC(O)R 3 , —OC(O)OR 3 , —N═CR 1 R 1 , —C(R 1 )═NR 1 , —C(R 1 )═N—O—R 1 , —P(O)(OR 3 )(OR 3 ), —S(O) 2 R 3 , —S(O)R 3 , —C(O)OC(O)R 3 , —NR 3 CO 2 R 3 , —NR 3 C(O)NR 1 R 1 , F, Cl, —NO 2 , —SO 3 R 3 , —CN, and combinations of two or more thereof; each R 3 is independently selected from the group consisting of C 1 to C 12 alkyl or cycloalkyl group, C 6 to C 20 aryl group, and combinations of two or more thereof; each R 5 is independently selected from the group consisting of H, F, Cl, C 1 to C 12 alkyl, C 1 to C 12 cycloalkyl, C 6 to C 20 aryl, —OR 3 , —CO 2 R 3 , —C(O)R 3 , —CHO, —CN, —CF 3 , and combinations of two or more thereof; each R 6 independently is selected from the group consisting of H, C 1 to C 12 alkyl, C 1 to C 12 cycloalkyl, C 5 to C 20 aryl, and combinations of two or more thereof; and each R 7 independently is selected train the group consisting of H, C 1 to C 12 alkyl, C 1 to C 12 cycloalkyl, C 6 to C 20 aryl, and combinations of two or more thereof.
