preparation Embodiment 1-1

[0164] [Preparation Example 1-1] Preparation of small-diameter diene-based rubber-like polymer (X-1)

[0165] Add deionized water (hereinafter abbreviated as water) 145 parts of potassium rosinate 1.4 parts of sodium oleate 0.6 part of sodium formaldehyde dihydrate 0.4 part of sodium sulfate in 10 liters of stainless steel autoclave equipped with stirring device and temperature control jacket 0.1 part of tert-dodecylmercaptan 0.3 part of dicumyl hydroperoxide 0.5 part

[0166] And flush the reaction vessel with nitrogen. Then, 1.4 parts of styrene monomer and 2.62 parts of 1,3-butadiene were added, and the temperature of the contents was raised. During the temperature rise, an aqueous solution consisting of 0.2 parts of anhydrous sodium pyrophosphate, 0.003 parts of ferrous sulfate heptahydrate and 5 parts of water was added at 50°C in order to initiate polymerization. At the same time, the polymerization temperature was controlled to be constant at 57° C., and monomers cons...

preparation Embodiment 1-2

[0167] [Preparation Example 1-2] Preparation of small-diameter diene-based rubber-like polymer (X-2)

[0168] Add water 195 parts sodium oleate 1.0 part N-lauroyl sarcosinate 0.8 part sodium formaldehyde dihydrate sodium sulfoxylate 0.1 part sodium sulfate 0.1 part hydrogen Dicumyl peroxide 0.2 parts

[0169] The reaction vessel was flushed with nitrogen while stirring. Then, 60 parts of n-butyl acrylate and 40 parts of 1,3-butadiene were added, and the temperature of the contents was raised. During the heating period, an aqueous solution consisting of 0.1 part of anhydrous sodium pyrophosphate, 0.003 part of ferrous sulfate heptahydrate, 0.0003 part of disodium ethylenediaminetetraacetic acid and 5 parts of water was added at 43°C to facilitate polymerization initiation. At the same time, the polymerization temperature was controlled to be constant at 55° C., and the polymerization was continued. After 8 hours, the residual 1,3-butadiene was removed under reduced pressure ...

preparation Embodiment 1-3

[0170] [Preparation Example 1-3] Preparation of acid group-containing copolymer latex (K-1)

[0171] Add water 200 parts potassium oleate 1.5 parts dioctylsulfuryl (sulfo) sodium succinate 2.5 parts sodium formaldehyde sulfoxylate into the reactor equipped with reactant injector, cooling tube, jacket heating device and stirring device 0.3 parts of ferrous sulfate heptahydrate 0.003 parts of disodium edetate 0.009 parts

[0172] Under a nitrogen purge, the temperature of the contents was raised to 60°C. When the temperature reached the point of 60°C, a mixture consisting of 88.5 parts of n-butyl acrylate, 11.5 parts of methacrylic acid and 0.5 parts of cumene hydroperoxide was continuously added dropwise over 120 minutes. After the dropwise feeding was completed, the reaction mixture was aged for 2 hours while maintaining the temperature at 60° C., thereby obtaining an acid group-containing copolymer latex (K-1) having a solid content of 33.0%, a polymerization conversion of 99%...

Abstract

A thermoplastic resin composition comprising 10 to 98 parts by weight of a graft polymer (1A) containing a rubber-like polymer (1G) having a diene unit content of 50% by weight or less, 2 to 50 parts by weight of a hydroxyl group-containing acrylic copolymer (1B) and 0 to 80 parts by weight of other thermoplastic resin (1F), wherein the rubber-like polymer (1G) is at least one selected from the group consisting of a diene-based rubber, a polyorganosiloxane-based rubber and an olefin-based rubber; and, a graft copolymer (2A) obtained by grafting a vinyl-based polymer to a (meth)acrylate-based rubber-like polymer (2G) expansion-treated with an acid group-containing copolymer latex (2K) wherein the (meth)acrylate-based rubber-like polymer contains two or more poly-functional monomer units.

Description

technical field [0001] The present invention relates to a thermoplastic resin composition excellent in matting performance, impact resistance, thermal stability and weather resistance. And, the present invention relates to a thermoplastic resin composition excellent in matting properties, impact resistance, surface hardness, molding processability (fluidity) and weather resistance. More specifically, the present invention relates to a thermoplastic resin composition which is not easily affected by kneading conditions and which exhibits excellent matting properties under a wide range of molding temperature conditions. Background technique [0002] Improving the impact resistance of resin materials obviously has great industrial application value, such as expanding the application range of materials, reducing the thickness and increasing the size of molded products, and so on. Therefore, various methods of improving the impact resistance of resin materia...
