Resin composition and molded article
By using a phosphorus-based flame retardant composition of Mn+(diethylphosphonic acid)-n and ammonium polyphosphate in the resin composition, a metallic supramolecular structure is formed, which solves the problem that ABS copolymers are difficult to self-carbonize without the addition of a carbonizing agent, achieving high flame retardancy and thermal stability, and is suitable for vehicle interior and exterior trim materials and electrical/electronic products.

AI Technical Summary
In the existing technology, ABS copolymers are difficult to form char with phosphorus-based flame retardants without the addition of charring agents, resulting in insufficient flame retardancy and thermal stability. In addition, the charring agents are expensive, which affects productivity.
A phosphorus-based flame retardant composition comprising 30% to 70% by weight of Mn+(diethylphosphonic acid)-n and 30% to 70% by weight of ammonium polyphosphate is used to achieve self-charring by forming metal supramolecular structures in the resin composition, thereby imparting flame retardancy and thermal stability.
Without the addition of a charring agent, the resin composition can self-char, exhibiting excellent flame retardancy and thermal stability, meeting the high flame retardancy requirements of the UL-94V test, and is suitable for a variety of products.
