Abstract Crystallization behavior of deproteinized natural rubber at −25°C was investigated by dilatometry in connection with the effect of long-chain fatty acid groups, esterified to the rubber chain, as well as free fatty acids and their esters. The overall crystallization rate decreased after removal of the acetone-extractable free fatty acids and their esters, while it increased significantly when the fatty acid groups esterified to natural rubber molecule were removed by transesterification with sodium methoxide. Both the acetone-extracted and transesterified rubbers showed a significant increase in the overall crystallization rate after the addition of 1 wt % stearic acid. The crystallization of acetone-extracted rubber was accelerated by the addition of 1 wt % methyl linoleate, a plasticizer of natural rubber, whereas it was suppressed in the case of transesterified rubber in which the esterified fatty acid groups were removed completely. The fatty acid groups esterified to natural rubber molecule gave rise to the accelerated crystallization of the rubber in conjunction with free fatty acids and their esters.

Abstract The amounts and types of HFA soaps found in latex did not vary greatly from sample to sample. Greater than 95% of the free HFA soaps were associated with the rubber phase of the latex. The distribution of fatty acid soaps were markedly different in the serum and latex samples. About 80–90% of the HFA soaps are in their free form, but only about 50% of the furanoic acid was in its free form. Titration results agree fairly well with the GC results and indicate that titration can be a useful measure of HFA.
