Abstract: This invention is based upon the discovered that crosslinked core-shell particles can be used as a filler in low cost emulsion styrene-butadiene rubber (ESBR) with excellent results being attained. In fact, such core-shell particle filled ESBR exhibits performance similar to silica filled solution styrene-butadiene rubber (SSBR) in terms of dynamic response, Payne effect, rebound and tan ? at 0° C. and 100° C. The utilization of such crosslinked core-shell particles in rubber compounds offers the additional advantage of weight reduction since the core-shell particles are significantly less dense than carbon black or silica fillers. The use of the crosslinked core-shell polymers of this invention in rubber formulations in place of silica also offers the advantage of not needing any expensive silane coupling agents to attain required levels of polymer/filler interaction. Accordingly, no silane coupling agent is used in the rubber compounds of this invention which leads to reduced cost.

Abstract: Strengthened filaments and fibers are realized by mixing and dissolving monomer and catalyst in a solvent into open-ended nanotubes to form a polymer precursor prior to polymerization in which the open nanotubes are filled with monomer and catalyst. The remaining steps for forming a stabilized filament may follow the conventional sequence.

These additional bonds provide additional mechanical strength. The number of bonds may be further enhanced by pretreating the nanotubes to create defects in the nanotubes to form sites along the inner and outer walls for additional polymer-to-nanotube bonds.
