Abstract
In this work, the crosslink density of uncured natural rubber with different initial moisture contents, 3.80%, 10.05%, 19.76%, 23.68%, respectively, dried by microwave at frequency of 2450MHz was studied using nuclear magnetic resonance spectrometer. Seen from the results, the effect of initial moisture content of wet natural rubber on crosslink density and processability were obvious. With the increment of initial moisture content of wet natural rubber, the crosslink density of natural rubber after microwave dried with the frequency of 2450MHz decreased gradually. The crosslink density and A(Mc) of natural with the lower initial moisture content was bigger compared with natural rubber with the higher initial moisture content.
