【Abstract】 In this paper,conducted an investigation in the law of tricomponent cocondensation of PTA (terephthalic acid )、 ADA (aliphalic acid ) and EG (ethylene glycol). The major process parameters of tricomponent cocondensation as follows: the time and the temperature of polymerization, the third monomer weight added into the system were analysed. The results indicated that they have a relation to co--polyester qualities.更多还原
