초록

The aim of this study is to synthesis basic resins for the preparation of PU flame-retardant coatings that contain phosphorus and chlorine. After synthesizing intermediates of tetramethylene bis(orthophophate) (TMBO) and neohexanediol trichlorobenzoate (TBA-adduct), the condensation polymerization was performed with the intermediates, 1,4-butanediol, and adipic acid to obtain four-component copolymers. In the condensation polymerization, the content of phosphorus was fixed to be 2%, and the content of trichlorobenzoic acid (TBA) that provides chlorine component was varied to be 10, 20, and 30wt%, and we designated the prepared modified polyesters containing chlorine and phosphorus as TTBA-10C, TTBA-20C and TTBA-30C. Average molecular weight and polydispersity index of the prepared TTBAs decreased with increasing TBA content because of the increase in the number of hydroxyl groups that retards reaction. We found that the thermal stability of the prepared TTBAs increased with chlorine content at high temperatures.
