Surface treating agent comprising modified propylene-ethylene copolymer, processes for preparing said surface treating agent, and use of said surface treating agent in the treatment of articles of an olefin resin. |
摘要 |
<p>A surface treating agent for fabricated articles of olefin polymers which is composed of an organic solvent solution of a modified polymer resulting from the graft copolymerization of a propylene-ethylene copolymer with maleic acid or maleic anhydride. The propylene-ethylene copolymer has a propylene content of 50 to 75 mole% and a crystallinity determined by an X-ray diffraction method of 2 to 20%. The amount of maleic acid or maleic anhydride grafted is 0.5 to 15% by weight. The modified polymer has an intrinsic viscosity of at least 0.3 dl<Sub>/</Sub>g, and is dissolved in the organic solvent in a concentration of 10 to 100 kg<Sub>/</Sub>m) of solvent. The treating agent can be prepared by dissolving the propylene-ethylene copolymer in the organic solvent before carrying out the grafting reaction or by carrying out the grafting reaction in a melt before adding the organic solvent. The treating agent is suitable for use as an undercoat for olefin polymer articles and improves the adhesion of a paint thereto.</p> |
