The present invention encompasses polymer compositions comprising aliphatic polycarbonate chains containing sites of olefinic unsaturation. In certain embodiments the aliphatic polycarbonate chains comprise sites of olefinic unsaturation capable of participating in radical-promoted olefin polymerizations. In certain embodiments, the invention encompasses composites formed by the polymerization or cross-linking of a combination of olefinic monomers and aliphatic polycarbonate chains containing sites of olefinic unsaturation.

modifications led to new PDE5 inhibitors with approximately 20-fold improved potency to inhibit PDE5 and no COX-2 inhibitory activity compared with celecoxib. PDE isozyme profiling of compound 11 revealed a favorable selectivityprofile. These results suggest that trisubstituted pyrazolines provide a promising scaffold for further chemical optimization to identify novel PDE5 inhibitors with potential for less
