かった。[0003] Conventionally, in order to meet this demand, since a feeling of wood cannot be obtained with the ABS resin itself, studies using a composition to which a cellulosic additive such as wood flour or paper is added have been conducted. For example, in order to obtain a woody feeling using an ABS resin, a hard resin composition containing wood powder and foamed has been manufactured. However, when general wood flour is added to the ABS resin, the acid is generated from the wood flour due to the acid generated from the wood flour.
There is a problem that the deterioration of the resin progresses, and not only the impact strength is lowered but also the color tone is significantly reduced, and
The BS resin composition tends to turn brown, and the color of wood powder of natural products may not be constant, and there is a problem that color management of the product is difficult. In addition, since impurities such as lignin contained in wood flour have a yellow tint, a large amount of pigment required for coloring is required, and when performing foam molding, this lignin tends to inhibit foaming. was there. As a means for solving these problems, Japanese Patent Publication No. 8-30382 discloses a method of suppressing the release of wood acid by supporting a white inorganic pigment on the surface of woody powder using a ball mill. However, in this method, the white pigment must be supported on wood powder, the number of steps is increased, the processing efficiency is low, and it is economically unsuitable, so that wood acid cannot be essentially suppressed.

秒数(t0 )と溶液の流下秒数(t)から次式(数1)
によって求める。The acrylonitrile component in the polymer component (A) obtained by removing the insoluble component in the mixture of methyl ethyl ketone and methanol 7: 3 from the ABS resin of the present invention is 10-3.
0% by weight and the reduced viscosity (η) of the polymer component (A).
sp / c) is 0.4 to 0.9 dl / g, preferably 0.4 to 0.80 dl / g, and more preferably 0.4 to 0.9 dl / g.
5 to 0.75 dl / g. Reduced viscosity 0.4 dl /
If it is less than 0.9 g, the impact strength is remarkably reduced, so that it is not preferable. If it exceeds 0.9 dl / g, the fluidity decreases,
The temperature at which molding can be performed is increased, and the hue is deteriorated, which is not preferable. Here, the reduced viscosity means that 0.25 g of the sea phase component (S) is precisely weighed, and dimethylformamide 5
The solution dissolved in 0 ml for 2 hours was heated to 30 ° C. using a Ubbelohde viscometer with a solvent flow time of 20 to 100 seconds.
With a value obtained by measuring in the environment, reduced viscosity falling seconds of the solvent (t 0) by the following equation from falling seconds of the solution (t) (Equation 1)
