Crosslink density distributions in natural rubber/nitrile rubber blends
thesis
posted on 2018-05-15, 10:26 authored by Michael V. LewanAn NMR technique has recently been developed to determine the crosslink density in each
phase of a polymer blend. This work uses the NMR method to study natural rubber
(NR)/acrylonitrile butadiene rubber (NBR) blends, in order that the cure system used to
vulcanize such blends can be optimized.
A standard injection moulding cure system for NR/Perbunan N1807 (18% acrylonitrile
content) gave much more crosslinking in the NBR phase. To reduce this imbalance a less
polar analogue of the accelerator was used, resulting in a more even distribution of crosslinks
but still with a bias towards the NBR. [Continues.]
