A process for continuously producing pipe by coating a particulate material with a gas curable resin, compacting the coated particulate material in an annular space, treating the compacted, coated particulate material with a curing gas to form a pipe having a porous wall structure, impregnating the porous walls of the pipe with an asphalt or resinous material, and, optionally, winding a reinforcing filament binder around the pipe.

Process for the continuous production of pipe from particulate materials

A process comprising synthesizing a liquid crystal polyester consisting essentially of recurring moieties of formulas: ##STR1## and moiety III or IV wherein III is ##STR2## wherein the mole ratio of moiety II to moiety III, when present, is 1:4 to 2:1 and wherein the mole ratio of moiety II to moiety IV, when present, is 2:8 to 1:9 and devolatilizing said liquid crystal polyester prior to shaping such polyester into an article and then shaping said devolatilized polyester into said article.

Melt processable optically anisotropic polymer processing

Styrene and hydroquinone are reacted to produce (1-phenylethyl) hydroquinone, i.e., ##STR1##

Synthesis of styrenated hydroquinone

Melt spinnable liquid crystal aromatic polyesters which are optically anisotropic in the melt phase are provided. The polyester is a poly [(1-phenylethylphenylene)/chlorophenylene terephthalate].

Melt processable optically anisotropic polyesters

Melt spinnable liquid crystal aromatic polyesters which are optically anisotropic in the melt phase are provided. The polyester is a poly [(1-phenylethyl)-phenylene/phenylene terephthalate].

Melt spinnable, liquid crystal aromatic polyesters which are optically anisotropic in the melt phase are provided.

Melt processable optically anisotropic polymers

Method and apparatus for producing an electrical conductor are provided comprising a doped polymeric material and an encasement means substantially impermeable to the dopant, the encasement means having matching surfaces in contact with the polymeric material to reduce the loss of dopant and an inert gas to occupy any voids between the surfaces.

Conductive polymers

Molded glass fiber parts are formed by depositing a phenolic resin and liquid polyisocyanate on the glass fibers as they are emitted from a fiber forming means, accumulating the glass fibers as a pack and molding the pack in contact with a tertiary amine to cure said resin and polyisocyanate and to produce a molded glass fiber part.
