Study on Molecular Weight of Natural Rubber with Different Initial Moisture Contents Dried by Microwave

Abstract:

In this article, the molecular weight of wet Natural Rubber (NR) with different initial moisture contents, 3.80%, 10.05%, 19.76%, respectively, dried by microwave at frequency of 2450MHz was investigated using GPC. It can be seen from the results that an obvious trend of M_n and M_w changes was presented. With the increment of initial moisture contents, M_n and M_w decreased gradually. The molecular weight distribution (d) increased with the initial moisture contents increment, but quite closer to each other.
