Title:
HIGH-TEMPERATURE SELF-CROSSLINKING-BASED FLAME-RETARDANT DROPLET-RESISTANT COPOLYESTER, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/254391
Kind Code:
A1
Abstract:
A copolyester, comprising structural units represented by [I], [II], [III] and [IV]. The number of structural units represented by [III] is 1-99% of the number of structural units represented by [I], and the number of structural units represented by [IV] is 0-99% of the number of structural units represented by [I]. Also provided are a preparation method therefor and an application thereof. Because an introduced high-temperature self-crosslinking group and an ion group can improve the melt viscosity and the melt intensity during burning of a copolyester, and effectively enhance the char-forming capability of the copolyester, the copolyester exhibits excellent flame retardance and droplet resistance. The preparation process for the copolyester is mature, convenient to operate, and easy to control and apply to industrial production.
