摘要
The present invention relates to a process for the preparation of homopolymer free plasma-grafted polypropylene-g-polyacrylic acid copolymer. More particularly, the present invention relates to a process for the preparation of homopolymer free plasma-grafted polypropylene-g-polyacrylic acid copolymer, wherein the polypropylene monofilament was exposed to oxygen plasma and was subsequently grafted with acrylic acid. Plasma activation of the polypropylene surface needs only few seconds. The graft polymerization of acrylic acid on polypropylene surface has been accomplished where the homopolymer formation is completely inhibited This has been achieved for the first time by using methanol and acetone as the additive. This is an innovative way to modify the materials without the homopolymer formation. Homopolymer free reaction helps in reusing the reaction bath several times making the process highly efficient.
