Blends of polyurethane (vibrathane- 5008 Uniroyal Co., USA) and hypalon (CSM-350 Du Pont, USA) prepared by three different blending techniques, have been studied, over the entire composition range. The processability of the polyurethane rubber was improved as a result of blending with CSM. The IR spectral analysis suggested that on heat treatment, without curatives, interchain crosslinking reaction occured between the two elastomeric phases. Experimental data revealed that, preheating of the preblends, before addition of curatives, enhanced the thermal properties of the blends. The degradation process were delayed along with the retardation in weight loss. The extractability of the single phase by solvent was also restricted on preheating, due to interchain crosslinking reaction. |
