A glass composition is disclosed which is formed from a mixture comprising one or a plurality of natural mineral zeolites and having a melting point in the range of from about 1000.degree. to about 1500.degree. C. The glass compositions of this invention can be formed into various glass articles, including flat glass, glass containers, glass fiber and glass foam.

Glass composition, its method of formation and products made therefrom

The unitary electrode (10) comprises a porous sheet (12) of fiberglass the strands (14) of which contain a coating (16) of conductive tin oxide. The lower portion of the sheet contains a layer (18) of resin and the upper layer (20) contains lead dioxide forming a positive active electrode on an electrolyte-impervious layer. The strands (14) form a continuous conduction path through both layers (16, 18). Tin oxide is prevented from reduction by coating the surface of the plate facing the negative electrode with a conductive, impervious layer resistant to reduction such as a thin film (130) of lead or graphite filled resin adhered to the plate with a layer (31) of conductive adhesive. The plate (10) can be formed by casting a molten resin from kettle (60) onto a sheet of glass wool (56) overlying a sheet of lead foil and then applying positive active paste from hopper (64) into the upper layer (68). The plate can also be formed by passing an assembly of a sheet ( 80) of resin, a sheet (86) of sintered glass and a sheet (90) of lead between the nip (92) of heated rollers (93, 95) and then filling lead oxide into the pores (116) of the upper layer (118).

Unitary plate electrode

Alpha-monoalkenes are addition polymerized by using an acyl halide (e.g., acetyl chloride)--Friedel Crafts catalyst complex and a monochloroalkane solvent (e.g., ethyl chloride); the acyl halide reacts in situ with the monomer to yield a polymeric ketone. The polymeric ketone is subsequently reacted with an aliphatic polyamine (e.g., tetraethylenepentamine) to yield a condensation product which is useful as a lube oil detergent.

Process, products and composition

A phosphorous halide (for example, PCl.sub.3) is present during the Friedel-Crafts polymerization of an alpha-monoalkene, resulting in the in situ formation of a phosphorylated polymer. Further reaction of the polymer with a polyamine converts phosphoryl groups to phosphonamide groups, yielding a product which is useful as a lube oil detergent.
