The invention relates to an electrode formed by the blending of dry active powdery electrode forming materials with an aqueous binder dispersion, and the subsequent adhering of the wet binder/dry active powdery electrode-forming materials blend to an electroconductive substrate, resulting in an electrode. The aqueous binder is preferably a fluoropolymer, and more preferably polyvinylidene fluoride (PVDF). The hybrid process provides the good dispersion and small particle size of a wet process, with the energy savings and reduced environmental impact of a dry process. The resulting electrode is useful in energy-storage devices.

The invention relates to a process aid for use in rigid thermoplastic compositions, and especially in rigid polyvinylchloride (PVC) compositions. The process aid is an acrylic terpolymer of methylmethacrylate, butyl acrylate and styrene at an optimal ratio to produce a significant reduction in melt process viscosity. The resulting reduction in extrusion melt torques enables manufacturers of rigid PVC products to have higher throughput production rates.
