| titleOfInvention | A kind of easily alkali contains intermingle with ester and preparation method thereof |
| abstract | The invention discloses a kind of easily alkali and contain intermingle with ester and preparation method thereof, described polyester is formed by terephthalic acid, ethylene glycol, m-phthalic acid diethyl diester-5-sodium sulfonate and silicon compound copolymerization.Its method is for first to obtain oligopolymer by terephthalic acid and ethylene glycol by esterification, again gained oligopolymer is carried out polycondensation and obtain polyester, catalyzer lithium compound is added in esterification and/or polycondensation stage, add m-phthalic acid diethyl diester-5-sodium sulfonate, silicon compound and stablizer phosphorus compound in the polycondensation stage, obtained easy alkali contains intermingle with ester.This polyester has excellent alkali dissolving out capability and good resistance toheat, can be used for the fields such as spinning, film, resin. |
