at least one modified polypropylene resin or resin composition (D) selected from the group consisting of:
a modified polypropylene (A) prepared by graft-polymerization of an unsaturated carboxylic acid or a derivative thereof onto a polypropylene (C),
a modified polypropylene (B) prepared by graft-polymerization of an unsaturated carboxylic acid or a derivative thereof and an unsaturated aromatic monomer onto a polypropylene (C),

摘要： The present invention provides a novel method for producing a filler-containing colored thermoplastic resin composition superior in pigment dispersibility and impact resistance. This method comprises melt kneading firstly at least a part of components of resin consisting of a thermoplastic resin (A) and/or a thermoplastic resin composition (B) with fillers (C), adding remainder of the resin, if any, with a pigment (E), and then further carrying out continuous melt-kneading.

摘要： A pigment master batch suitable for filler-containing polypropylene compositions is provided. This pigment master batch comprises 100 parts by weight of a propylene homopolymer having a melt flow rate of at least 10 g/10 min. and 30 - 200 parts by weight of a processed pigment prepared by using a metallic salt of a fatty acid, a polyethylene wax or a polypropylene wax as a dispersion medium for pigment. A filler-containing polypropylene composition in which the above pigment master batch is incorporated is superior in dispersibility and balance of properties and can easily be processed into molded articles which are superior in balance of properties such as heat resistance, impact resistance and rigidity.

摘要： The modified polypropylene resin composition of the present invention comprises a blend of a resin composition composed of polypropylene type resin (C) selected from the group consisting of a modified polypropylene (A) obtained by graft copolymerizing an unsaturated carboxylic acid or a derivative thereof and an unsaturated aromatic monomer onto a polypropylene, and modified polypropylene (A)/polypropylene (B) composition, and
a saturated polyester resin (D),
an epoxy group containing copolymer (E), and
a basic compound (F) optionally added as a reaction accelerator.
The modified polypropylene resin composition according to the present invention is not only good in molding processability but also markedly effective in that it can give molded products much superior in physical properties to those obtained from individual polymers constituting the thermoplastic resin composition.
The novel modified polypropylene resin composition provided by the present invention can easily be processed into a molded product, a film, a sheet or the like by a molding method usually used for molding thermoplastic resins, for example, injection molding, extrusion molding or the like, giving a product which has a very good balance among stiffness, heat resistance, impact resistance, scratch resistance, coating properties, oil resistance, chemical resistance, water resistance, etc., and is excellent in appearance uniforming and smoothness. It can be advantageously used for a purpose requiring especially high heat resistance and impact resistance, in particular, low-temperature impact resistance.摘要翻译： 本发明的改性聚丙烯树脂组合物包含由聚丙烯类树脂（C）组成的树脂组合物的共混物，所述树脂组合物选自由不饱和羧酸或其衍生物接枝共聚得到的改性聚丙烯（A）和 不饱和芳族单体聚丙烯，改性聚丙烯（A）/聚丙烯（B）组合物和饱和聚酯树脂（D），含环氧基共聚物（E）和碱性化合物（F）任选加入作为反应 加速器。 根据本发明的改性聚丙烯树脂组合物不仅具有良好的模塑加工性，而且显着有效，因为它可以使得成型产品的物理性能比构成热塑性树脂组合物的各种聚合物获得的成型产品更优异。 通过本发明提供的新型改性聚丙烯树脂组合物可以通过通常用于模制热塑性树脂的模制方法，例如注射成型，挤出成型等，可以容易地加工成模制品，薄膜，片材等 赋予在刚性，耐热性，耐冲击性，耐刮擦性，涂布性，耐油性，耐化学性，耐水性等方面具有非常好的平衡的产品，外观均匀且平滑。 它可以有利地用于需要特别高的耐热性和耐冲击性，特别是低温耐冲击性的目的。
