Abstract: A flexible and detachable toothbrush for allowing the head of the toothbrush to flex to 180 degree and to be replaced when it becomes worn or damaged. The inventive device includes head having curve to the back of head in order to rotate on handle with round surface at tip. The simplified disconnection of head from handle to allow head to be removed when it becomes worn and replaced with new head and bristles without having to replace the handle.

Abstract: Better wet-out of glass fiber, lower viscosity of the resin mix which allows for higher filler loadings and better stability are the improvements of this invention. The compositions are prepared by an improved process which comprises mixing a vinyl ester resin having pendant half ester groups and a copolymerizable monomer with a polymeric low profile additive, glass fiber reinforcing material, CaCO.sub.3 filler and a viscosity reducing agent comprising a copolymer of a maleic acid half ester of a polyethylene glycol having a molecular weight of about 1450 to 6000 and a monoalkenyl aromatic monomer. A chemical thickening agent such as magnesium oxide may also be added.
