FLAME RESISTANT POLYESTER FIBER

摘要

The novel polyester fiber was produced from the addn. of (I) by 4-10 wt.% bromine content against a whole polymer at the opt. rxn. step to reacting dicarboxylic acid or its ester with diols at two thermo- step(140-240≦̸C and 240-290≦̸C). Where R=2-4C alkyl; n=0-4 integer; X=- C(Me)2-, -SO2-, -CH2-. Prepg. fiber have lowwhite-dust and are easily mfg. ; it prevents toxic gas from forming and discoloration by decompsn.
