Moreover, the proportion of humic compounds in EPSLoP-ProS and EPSHiP-ProS were ∼6 and ∼16–fold higher than that in EPSMono-ProS, respectively. The accumulation of humic compounds in EPS increased the unsaturation degree of EPS molecules, and thereby reduced the energy requirement for ...
Blends of higher and lower unsaturation elastomers are cured by partially curing a lower unsaturation elastomer or blend of elastomers, then mixing the partially curing lower elastomer(s) with a higher unsaturation elastomer or blend of elastomers and curing the blend. The lower elastomer may be ...
