Chapter 3 Elastomer blend and compatibility: a flow visualisation study
-
Dipak Kumar Setua
Abstract
An experimental study on the influence of several potential compatibilising agents on mixing of binary blends of (i) nitrile rubber (NBR) and ethylene-propylene copolymer (EPM), (ii) polyisoprene (IR) and EPM, and (iii) epoxidised natural rubber (ENR) and EPM have been made. The compatibilising agents used were different types of elastomers, for example, (a) chlorinated polyethylene (CM), (b) chlorosulfonated polyethylene (CSM), (c) chlorinated isobutylene isoprene copolymer (CIIR), (d) transpolyoctenylene (TOR), and (e) polybutadiene (BR). These compatibilisers have varied levels of relative polarity, solubility parameter, and chemical compositions. Addition of a suitable compatibiliser, in a small concentration, in different binary elastomer blends was found to increase the rate of mixing with a corresponding reduction of the blend homogenisation time. Further, the addition of an effective compatibiliser generates finer phase morphology with respect to dispersion and distribution as well as a substantial reduction of size of final dispersed particles in the matrix phase.
