The present invention relates to polyesters prepared from benzene, cyclohexene and cyclohexane compounds having carboxylic acid groups at the 1 and 4, and optionally the 2, positions, such as terephthalic acid or dimethyl terephthalates, and alkylene glycols, such ethylene glycol or 1,4-butane diol. The invention also relates to processes for preparing such polyesters. The invention also relates to such polyesters derived from starting materials derived from renewable resources.
本发明涉及由苯、环己烯和环己烷化合物制备的聚酯,其在1和4位置,以及可选的2位置具有羧酸基团,例如对苯二甲酸或二甲基对苯二甲酸酯,以及乙二醇或1,4-丁二醇等碳链二醇。该发明还涉及制备此类聚酯的方法。该发明还涉及从可再生资源衍生的起始材料制备的这种聚酯。
