ESTER COMPOUNDS, METHOD OF PREPARING THEREOF, AND AGENT FOR PREPARATION OF FIBER |
摘要 |
FIELD: chemical industry. SUBSTANCE: ester compounds of formula I (R ) wherein R is ethylene residue or alkyl substituted alkylene residue having 2-4 carbon atoms in alkylene chain with methyl, ethyl, propyl or isopropyl as alkyl substituent; x plus y are integers from 2 to 35 and are zero; <EMI ID=0.309 HE=6 WI=15 TI=CHI> is <EMI ID=0.310 HE=21 WI=84 TI=CHI>; z is zero or integer from 1 to 12 or phenylene or vinylene residue; m is integer from 1 to 30. Compounds of formula I and mixtures thereof have simultaneously advantage of being readily detachable biologically when polyurethane materials are slightly swollen and are suitable as agents for preparation of fiber, especially as texturing agents and components of texturing agents. Oligoesters I are prepared by esterification of diol of formula II with dicarboxylic acid of formula III. EFFECT: more efficient preparation method. 12 cl, 16 ex, 4 tbls
