The present invention relates to a heat resistant additive for a novel polymer resin and a polymer resin composition comprising same, and more specifically, to a heat resistant additive for a polymer resin containing a thio-compound having a specific structure, and to a synthetic resin comprising same. The polymer resin composition comprising the heat resistant additive of the present invention has superior heat stability even at a high temperatures of more than or equal to 200℃ without requiring the use of an additional heat resistant additive, wherein the heat resistant additive has a high molecular weight and thus has low volatility, thereby enabling the manufacturing of an eco-friendly polymer resin. |
