This invention concerns a novel method to produce thermosets such as epoxies and polyurethanes comprising nano-cellulose. The method comprises contacting primarily water-bourne dispersed nano-cellulose with liquid thermoset precursors, specifically epoxy or amine in the case of epoxies, or glycols or similar in the case of polyurethanes. Nano-cellulose transfers to the organic phase, and water is removed at temperatures below 100&#xb0; C. Thereafter the organic phase comprising nano-cellulose can be mixed with the reactive counterpart to yield nano-composites with improved properties. The products can be used for composite articles, coatings, adhesives, sealants, and other end-uses. Preferred embodiments are described in detail.

The subject invention pertains to thermoplastic marking compositions comprising a binder, which in turn comprise at least one homogeneous polymer. Accordingly, the subject invention provides a thermoplastic marking composition comprising: (a) from 10 to 80 weight percent of a binder, which in turn comprises: (i) from 1 to 99 weight percent of at least one homogeneous polymer; (ii) from 5 to 70 weight percent of at least one tackifier; (iii) from 0 to 10 weight percent of a polyethylene which has pendant acid functionality moieties of a non-functionalized wax; and (iv) from 0 to 20 weight percent of a plasticizer; and (b) from 20 to 90 weight percent of an inorganic filler. The subject formulations are usefully applied via spray, screed, and extrusion techniques.
