Thermally decompose, the gas that generates at the time of molding increases, the ventilation hole plug of mold or pollution and cause appearance of molded articles to be deteriorated.
When using pas resin, up to now, such as stearic acid is used sometimes for the mold releasability improved when forming
Higher fatty acid metal salt as magnesium.
The invention of PAS based resin composition is described in No. 4027734 bulletins of Japanese Patent No., which is
Amorphism alpha olefin copolymer and fatty acid metal are applied in combination with 0.2~3.0 mass % of total amount relative to pas resin etc.
(claims) made of salt.
And describe following the description：The project to be solved is to provide the excellent PAS of the mold releasability in injection molding
Based resin composition (the 0003rd section).
In embodiment 1,2 (table 1), describe comprising PPS resin, glass fibre, ethylene-propylene copolymer, stearic acid
The composition of magnesium, and show, release property (the 0013rd section of measuring method) is good.
Summary of the invention
The issue of the present invention is to provide can obtain showing excellent mechanical strength, especially excellent impact strength
The pas resin composition of molded product and the molded product obtained by the composition.
The present invention provides pas resin composition, contains：
