Abstract
The present invention encompasses polymer compositions comprising aliphatic polycarbonate chains containing functional groups that increase the polymer's ability to wet or adhere to inorganic materials. In certain embodiments, chain ends of the aliphatic polycarbonates are modified to introduce silicon-containing functional groups, boron-containing functional groups, phosphorous-containing functional groups, sulfonic acid groups or carboxylic acid groups.
Claims39
An epoxide CO2 copolymer composition comprising epoxide CO2 copolymer chains wherein:
- one or more chain ends of at least a portion of the epoxide CO2 copolymer chains within the epoxide CO2 copolymer composition have a formula:
- where,
- R1, R2, R3, and R4 are, at each occurrence in the polymer chain, independently selected from the group consisting of —H, fluorine, an optionally substituted C1-30 aliphatic group, and an optionally substituted C1-20 heteroaliphatic group, and an optionally substituted C6-10 aryl group, where any two or more of R1, R2, R3, and R4 may optionally be taken together with intervening atoms to form one or more optionally substituted rings optionally containing one or more heteroatoms and/or one or more sites of unsaturation;
- —Q— is a bivalent or multivalent moiety;
- each Z comprises an adhesion enhancing functional group independently selected from the group consisting of:
- silicon-containing functional groups, phosphorous-containing functional groups, —SO3H, —CO2H, and —N(Rα)3+ where each Rα is at each occurrence, independently selected from the group consisting of optionally substituted phenyl, and optionally substituted C1-12 aliphatic;
- and
- α is an integer from 1 to 4 inclusive;
- the epoxide CO2 copolymer composition is characterized in that, on average in the composition, the percentage of carbonate linkages in epoxide CO2 copolymer chains is 90% or greater;
- the number average molecular weight of the epoxide CO2 copolymer composition is less than about 20,000 g/mol;
- and
- further, wherein one or more chain ends of at least a portion of the epoxide CO2 copolymer chains within the epoxide CO2 copolymer composition have a formula:
- where,
- R1, R2, R3, and R4 are, at each occurrence in the polymer chain, independently selected from the group consisting of —H, fluorine, an optionally substituted C1-30 aliphatic group, and an optionally substituted C1-20 heteroaliphatic group, and an optionally substituted C6-10 aryl group, where any two or more of R1, R2, R3, and R4 may optionally be taken together with intervening atoms to form one or more optionally substituted rings optionally containing one or more heteroatoms and/or one or more sites of unsaturation.
