FLAME RESISTANT POLYESTER FIBER

FLAME RESISTANT POLYESTER FIBER

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-. Pr...
