The invention is directed to a phosphonate composition having flame retardant properties. The phosphonate composition of the invention has the general formula (I): wherein R1 and R2 are independently CI-C4 alkyl, R3 is H or C1-C4 alkyl, and R4 is linear or branched C9-C22 alkyl, C9-C22 cycloalkyl, C9-C22 aryl or C9-C22 aralkyl and n=0 or 1. The invention is also directed to a method of producing the phosphonate composition having flame retardant properties. 본 발명은 난연성을 갖는 포스포네이트 조성물을 제공하는 것을 목적으로 한다. 본 발명의 포스포네이트 조성물은 하기 일반식으로 표시된다: 상기 일반식 (I)에서, 각각의 R및 R는 독립적으로 C∼C알킬이고, R는 H, 또는 C∼C알킬이고, R는 선형 또는 분지형의 C∼C알킬, C∼C사이클로알킬, C∼C아릴, 또는 C∼C아랄킬이며, n= 0 또는 1임. 또한, 본 발명은 다른 목적은, 난연성을 갖는 포스포네이트 조성물의 제조 방법을 제공하는 것이다.
