Abstract
Vulcanisation of the NR phase of a NR/EPM blend during mixing is effected by using a very active accelerated-sulphur cure system. The crosslinking of the NR phase albeit at a low level results in a change in the blend rheology. A change in the blend morphology accompanies this process; the EPM is a disperse phase within a NR matrix in the control blend but is present as part of a co-continuous blend morphology in the dynamically vulcanised blend. The size of the domains of both polymers is also reduced in the dynamically vulcanised blend. When properly compounded with clay and oil the dynamically vulcanised blends are readily processed scoring 13 in extrusion through a Garvey die. The properties of vulcanisates derived from these blends are generally good.
