Abstract: This invention is based upon the unexpected finding that a hydrocarbon traction resin can be dispersed into the oil used in making an oil extended emulsion and solution rubbers to attain improved performance characteristics. For instance, this technique allows for the hydrocarbon traction resin to be incorporated into the rubber at a higher level than would ordinarily be possible using conventional mixing techniques. In tire tread compounds this provides improved wet traction characteristics without compromising cured stiffness (dry traction) and ultimate properties (chip/chunk resistance). This technique can be used to incorporate a resin into virtually any synthetic rubber that can benefit from being oil extended. It is of particular value in making resin modified solution styrene-butadiene rubber (SSBR), emulsion styrene-butadiene rubber (ESBR), high cis-1.4-polybutadiene rubber, and synthetic polyisoprene rubber which are formulated for use in tire tread compounds.

Abstract: This patent describes formaldehyde free or formaldehyde reduced binders useful, for example, in a fiber based composite material such as glass or other mineral fiber insulation, non-woven fabric or wood-based board. In one example, melamine is used as an acidic solution or a salt. The salt or solution is used to create an aqueous binder with other components such as a polyol and a crosslinker. A preferred polyol is a nanoparticle comprising high molecular weight starch. In other examples, binders include mixtures of a polyol with urea and a crosslinker. In other examples, a multi-component nanoparticle is made by reacting a polyol such as starch in an extruder with an insolubilizer such as melamine or urea. The resulting particles are mixed with water, optionally with other components such as an additional crosslinker, to create an aqueous binder.
