PURPOSE:To improve safety by forming the above compsn. of the compatibilized matter of polymethyl methacrylate(PMMA) and polyvinylidene fluoride(PVdF). CONSTITUTION:This compsn. consists of the compatibilized matter of the PMMA and the PVdF. The PMMA is a homopolymer consisting of methyl methacrylate and the mol.wt. thereof is 10000 to 1000000. The PVdF is a homopolymer of vinylidene fluoride and the mol.wt. thereof is 10000 to 1000000. The compatibilized matter of the PMMA and the PVdF is obtd. by kneading, for example, both pellets in the molten state above 200 deg.C. The excellent in-vivo stability and stainproofing property are obtd. in this way and the safety is improved. |
