摘要
本文介绍了一种用于聚酯缩聚的、新型高性能催化剂“C 94”。它是碳 /硅混合氧化物 ,抗水解 ,无毒 ,对环境无害。这种催化剂适合所有生产PET的常规工艺。用这种新催化剂制取的PET在性能上与普通PET几乎一样 ,但若制备工业用丝 ,更具优势。C - 94制取的PET染色更快 ,温度更低 ,染料使用量更少 ,而且废水中不含有害成分。
A new, highly active catalyst for the polycondensation of polyester is presented. This catalyst, which is called 'C 94', is based on hydrolytically stable titanium/silicon mixed oxides, components that are environment friendly and harmless. This catalyst is suited for all common routes of PET production. PET made with this new catalyst shows nearly the same technical properties as conventional PET but has several advantages for the textile industry. C 94 PET dyes faster or with lower temperature and with less dyestuff and the finishing wastewater is free of ha zardous components.
