resin modifier

In the surface of the molded article to corona discharge treatment or a plasma treatment method, there are treated as time goes by, will reduce the problem of wettability. Moreover, the polyolefin resin composition to the surface active agent is added to the molded article made of the method, there is added to make the modification effect if the added amount of full, the original molded polyolefin resin base material originally has a mechanical strength (tensile elastic modulus, impact resistance, etc. hereinafter.) be damaged or a surfactant molded article from leaking problems, eager to improve.
The present invention seeks to provide mechanical strength without prejudice to the polyolefin resin substrate under the conditions of imparting excellent water wettability polyolefin resin modifier.
In order to solve the above problems, the present inventors have intensively studied to complete the present invention. That is, the present invention comprising a polyolefin (A) and unsaturated dicarboxylic acids (anhydrides) (B) the structural unit having 50 ~ 250mgK0H / g of acid value of the copolymer (X) is a polyolefin resin improving agent (K); containing the modifier, and (K) and the polyolefin resin (E) of a polyolefin resin composition.
 The present invention is a polyolefin  resin modifier , the modifier comprising the polyolefin resin composition molded article formed by molding has the following effects.
