영문 초록

The aim of this study is to enhance the flame retardancy by the synergism effect of phosphorus and bromine groups. The flame-retardant polyurethane coatings containing phosphorus and bromine compounds were synthesized. After synthesizing the intermediate products of tetramethylene bis(orthophosphate) (TBOP) and trimethylolpropane/2,3-dibromopropionic acid (2,3-DBP) [2,3-DBP-adduct], the condensation polymerization was performed with four different monomers of two intermediate products, 1,4-butanediol, and adipic acid to obtain four-components copolymer. In the condensation polymerization, the content of phosphorus was fixed to be 2wt%, and the content of 2,3-DBP that provides bromine component was varied to be 10, 20, and 30wt%, and we designated the prepared modified polyesters containing phosphorus and bromine as DTBA-10C, -20C, -30C. Average molecular weight and polydispersity index of the preparation of DTBAs were decreased with increasing 2,3-DBP content because of increase of hydroxyl group that retards reaction. We found that the thermal stability of the prepared DTBAs increased with bromine content at high temperature.
