The present invention encompasses CO2-based polycarbonate polyols that do not degrade from the chain ends to form cyclic carbonate. Importantly, the inventive polyol compositions retain —OH end group functionality desirable for thermoset applications.
The present invention encompasses compositions comprising a polyurethane and a block copolymer with at least two homopolymer subunits. In one aspect, compositions of the present disclosure are coating compositions. In another aspect, compositions of the present disclosure are adhesive compositions.
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.
In one aspect, the present invention encompasses compositions of sustainable polycarbonate polymers, methods of producing such polymers, and methods for evaluating whether certain constituents of a polymer chain are derived from biomass or a fossil carbon source.
