Abstract
Disclosed herein is a symmetric cyclic phosphonate compound represented by the following Formula 1, a method of preparing the same and a flame retardant styrenic resin composition including the same: wherein R1 and R2 are each independently hydrogen, C1-C6 alkyl or C6-C20 aryl. The styrenic resin composition employing the symmetric cyclic phosphonate compound exhibits good flame retardancy and impact strength, does not release halide gas during preparation or combustion of the resin composition, and thus is environmentally friendly.
Claims13
A flame retardant styrenic resin composition comprising:
- about 100 parts by weight of a base resin comprising (A) a styrenic resin and (B) a polyphenylene ether resin;
- and
- about 0.5 to about 50 parts by weight of (C) a symmetric cyclic phosphonate compound represented by the following Formula 1 or a combination thereof;
- wherein R1 and R2 are each independently hydrogen, C1-C6 alkyl or C6-C20 aryl.
