    摘要: The present invention provides a method for manufacturing a resin composition by which a polyester resin composition with excellent mechanical properties can be manufactured at low cost, and a resin composition manufactured thereby. A raw material composition containing a polyester resin, a polyolefin resin and a compatibilizer is kneaded in the presence of moisture. Each of the components may be mixed so as to prepare the raw material composition and kneaded thereafter, or may be mixed during the kneading so as to obtain the raw material composition. The raw material composition may contain an additive such as a plant tissue-derived component and an inorganic filler, as necessary. Moreover, in the kneading step, the kneading preferably is conducted while at least one of the components of the raw material composition except the moisture is added into the raw material composition, as necessary.

    摘要: Alicyclic carboxylates, such as alicyclic norbonane sodium dicarboxylate, may be used in relatively small amounts as crystallization nucleating agents for foamed polypropylene. The alicyclic carboxylates give improved cell structures at lower proportions than conventional crystallization nucleating agents. The use of alicyclic carboxylate crystallization nucleating agents together with conventional nucleating agents may help give lower density polypropylene foams across a broader melt temperature range.

    摘要: The present invention provides a composite resin composition comprises A) polypropylene-based resin by 100 weight portions, (B) organized denatured clay by 0.1 to 50 weight portions, and (C) maleic anhydride denatured polypropylene by 0.5 to 30 weight portions, in which the maleic anhydride denatured polypropylene satisfies the following conditions that the quantity of not-reacted maleic anhydride is outside a limit for quantitative analysis; that the percentage of acid content against a number of polymer chains is not less than 0.8 and not more than 2.0; that the molecular weight distribution is not less than 2.5; that the percentage of components with the molecular weight of 10,000 or less is not more than 0.5% by weight; and that the ultimate viscosity (null) is 1 or more. A supercritical gas is infiltrated in this composite resin composition for degassing to obtain resin foam. With the operations above, bubbles are formed finely and homogeneously at the high density and high solidity is provided.
