Improving resistance to low temperature crystallization in NR/ENR-25 blends,ture because the damping derives from relatively high glass transition temperatures (..). An alternative approach of using natural rubber (NR) with high levels of carbon black and oil but relatively low crosslink densities limits the degree of damping attainable and gives rather poor physical properties.

,Introduction — the book and rubber blends,enerality of approach. Only certain blend systems are considered, even where an approach might logically be also applicable to another combination of elastomers. The work described was also constrained by falling within a fixed time frame, and scope for further advances remains in many of the more practical areas.

Estimation of crosslink density by solid-state NMR spectroscopy,whether the technique for estimating crosslink densities in the component rubbers of a vulcanized blend can be translated to a solid-state NMR spectrometer by adopting appropriate operating procedures, and thereby facilitate the estimation of crosslink densities in vulcanized blends.

Natural rubber/ENR-25 blends,g also show a strong dependence of properties on temperature, whilst the use of high levels of filler and plasticizer, generally used with a low level of curatives, leads to unsatisfactory physical properties.
