ABSTRACT:
New polymeric compositions comprising polyolefin-polycarbonate-polyolefin triblock copolymers and a method of preparation comprising reacting a monohydroxy polyolefin in an organic solvent with a carbonate precursor such as phosgene, adding the resultant mixture to bisphenol A, water, an organic solvent and an acid acceptor such as sodium hydroxide, controlling the pH of the polymerizing mixture at 11 and, after the polymerization is complete, decreasing the pH to 8 and recovering the product.
