The invention discloses a plasticizer, a plasticizer composition, a heat resistant resin composition and a preparation method thereof, and when the plasticizer is used for a heat resistant resin composition, the elongation retention ratio thereof can be improved, and the aging resistance and heat resistance can be enhanced. And can exhibit better tensile strength, tensile strength retention rate or heat loss before and after heating, etc., so it helps to enhance the physical properties of the heat resistant resin. |
