BIOBASED POLYESTERS

摘要

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 preparingsuch polyesters. The invention also relates to such polyesters derived from starting materials derived from renewable resources.
