A new artificial veneer resembling expensive natural wood veneers can be manufactured by a new method from an inexpensive raw log, wherein a wood-meal containing veneer is first obtained by slicing in quartersawn grain direction a primary artificial flitch of many material veneers of the inexpensive raw log stacked and bonded with a wood-meal layer interposed between them, and many of the wood-meal containing veneers are stacked and bonded, with the material veneers alternately interposed as they stand or as further processed, into a secondary curved artificial flitch, which is sliced in flatsawn grain direction into the new artificial veneers presenting a grain pattern similar to that of the expensive wood with minutely raised and recessed uneven surface at simulated porous zones by the wood-meal containing veneers.

A composition for forming inorganic hardened products, which comprises a precursor for forming TSH, gypsum and a cement material selected from the group consisting of Portland cement, blast furnace slag and a mixture thereof, the amount of each ingredient satisfying the following relations by weight:

Composition for forming inorganic hardened products and process for

A process of producing calcium aluminate monosulfate hydrate by reacting a mixture of a lime component, an alumina component, a calcium sulfate component, and water at a temperature of from about 100.degree. C. to about 200.degree. C. By the process of this invention, the aimed product having a high purity is obtained at a high yield without need of high temperature for the reaction. The product obtained is useful as building materials.

Process of producing calcium aluminate monosulfate hydrate

A two-stage process for producing a three-component graft copolymer of 1,2-polybutadiene, glycidyl methacrylate and a second monomer. By first reacting glycidyl methacrylate on the polymeric substrate and then reacting the second monomer to form a non-crosslinked graft copolymer, high curing rates are obtained. By forming a solvent solution of the grafted product, an epoxy hardener and a radical polymerization initiator, a varnish suitable for forming dielectric prepregs is obtained.
