Problems solved by technology

The aromatic ring-containing ester polymer has a large steric hindrance on the main chain and poor flexibility of the molecular chain, resulting in a slow crystallization rate, which has a negative impact on the processing performance and physical and mechanical properties of the aromatic ring-containing ester polymer. , also reduces the efficiency of industrial production and the quality of corresponding products
However, there are few reports on the promotion of crystallization of 2,5-furandicarboxylates

Abstract

The invention discloses an organic nucleating agent used for an ester polymer containing aromatic ring. The chemical structural formula of the nucleating agent is R2-NH-C(O)-C(O)-NH-R1-NH-C(O)-C(O)-NH-R3, wherein R1, R2 and R3 are independently selected from hydrocarbon group or hydrocarbon group containing substituent groups. The invention also discloses an aromatic ring ester polymer resin composition comprising the nucleating agent, and a preparation method thereof. The fast-crystallization aromatic ring ester polymer resin composition obtained with the preparation method provided by the invention has characteristics of high crystallization temperature, high crystallization speed, short half-crystallization time, and the like. With the method, forming period can be shortened, cost can be reduced, and performance can be improved. The preparation method is simple and environment-friendly. With the method, industrialization is easy to realize.
