関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to 1M resin compositions, and more particularly to polycarbonate resin compositions with improved bulk and impact resistance.
ポリカーボネート樹脂は高度の耐衝撃性を具備し、自己
消火性であり、耐熱性が他の樹脂に比して高り、シかも
電気的特性及び寸法安定性が優わていることから、エン
シェアリングプラスチックとして広く使用されている。Polycarbonate resin has a high degree of impact resistance, is self-extinguishing, has higher heat resistance than other resins, and has superior electrical properties and dimensional stability. Widely used as ring plastic.
しかし、ポリカーボネート樹脂には次のような欠点があ

’厚さ)では脆性破壊を示し、厚さが厚い領域で衝撃強
さが低下する。1) Since polycarbonate resin has low solvent resistance, large-sized or complex-shaped molded products with large residual stress may cause stress cracks when exposed to certain solvent atmospheres. 2)
When using polycarbonate resin as a molded product,
The impact strength is highly dependent on the thickness of the molded product, for example 3.
In the isot notched impact test of 2 m thick (178 # thick), ductile fracture was shown, whereas 6.4 W (1/4
'thickness) shows brittle fracture, and the impact strength decreases in the thicker region.
このような欠点のため、ポリカーボネート樹脂は高い衝

The introduction of 95% by weight of polycarbonate resin, 1 to 50% by weight of polycarbonate resin, and acrylic core/outer shell polymer is disclosed in JP-A-56-9594.
No. 8 discloses these methods for the purpose of improving the impact resistance of aromatic polyesters. However, none of the above patent publications suggests objects or advantages similar to those of the present invention. In particular, it cannot be inferred from the above patent publication that the composition of the present invention has high solvent resistance.
