Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a resin composition containing borifuenylene sulfide, and particularly relates to a resin composition containing borifuenylene sulfide (hereinafter referred to as PP).
The present invention relates to a resin composition in which the brittleness of the resin against impact has been improved.

(Prior art and its problems) PPS resin has excellent heat resistance, flame retardance, chemical resistance, and high rigidity, and is extremely useful as an engineering plastic, but it has the disadvantage of being brittle against impact. Therefore, resin composites have been proposed that utilize the excellent properties of PPS while improving its drawbacks.

In the past, there have been many attempts to solve the drawbacks of each resin by blending resins with different properties (
being done.

For example, Japanese Patent Application Laid-Open No. 156561/1989 discloses a resin made of PPE and PPS to which PPS is added to improve the moldability and flame retardancy of borif nylene ether (hereinafter sometimes referred to as PPE). A composition is disclosed.

However, different types of polymers usually have poor compatibility, and as shown in Japanese Patent Application Laid-open No. 50-156561 (2PP
When E and PPS are simply mixed, the resulting resin composition is brittle and does not have sufficient mechanical strength.

In JP-A-64-36645, in order to improve the mechanical strength, P[][ which had been modified with a modifier that modifies the ethylenic double bond and the carboxyl group or the acid anhydride group was mixed with PPS. It is disclosed that However, the impact strength of the resin composition obtained here is still insufficient, and its brittleness has not yet been resolved.
