摘要: POLYPERFLUOROPOLYENES SUCH AS POLYPERFLUOROBUTADIENE ARE REACTED WITH FLUORINE TO EITHER PROVIDE A STAURATED POLYMER CHAIN AND/OR CREATE REACTIVE SITES ON THE POLYMER CHAIN WHICH IS THEN FOLLOWED BY EXPOSURE TO A MONOMERIC SPECIES WHICH UNDREGOES FREEN REDICAL POLYMERIZATION TO GRAFT THE MONOMR ONTO THE POLYPERFLUOROPOLYENE.
