PolyDL-lactide (PDLLA) and the block copolymer, polyDL-lactide-b-poly(ethylene glycol)-b-polyDL-lactide (PELA) were used as the microsphere matrix to encapsulat
Polycyclotrimerization and polycoupling of acetylenic monomers respectively furnish hyperbranched polyarylenes and polyynes with high molecular weights (up to 1
According to the present theories of plastic toughening, it is impossible to enhance the toughness, stiffness and/or heat resistance of plastics simultaneously
A new process for lamination of polymer films by 'bulk surface photografting' has been developed. The chemical component of the invention is that the cu
