Fibre Chemistry Aims and scope

Conclusions

Contamination of terephthalic acid with 4CBA causes a decrease in the whiteness of the finished polyethylene terephthalate and the appearance of branched structures due to reactions of the aldehyde group.

To obtain high-quality polyethylene terephthalate with good color characteristics, it is very advisable to use stabilizers which reduce the aldehyde group in 4CBA, phosphites for example.
