Styrene or other anionically polymerizable monomer is anionically homopolymerized in a dispersion using a non-solvent, e.g., hexane using three or more stages to obtain spherical microparticles, e.g., 2-5 microns, with a narrow size distribution.

Multi-stage anionic dispersion homopolymerization to form microparticles

Crystalline isotactic poly(para-methylstyrene) previously unreported in the literature is prepared by polymerizing para-methylstyrene with a TiCl.sub.3 /aluminum alkyl catalyst and fractionating the product to obtain a crystalline fraction with a crystalline melting point of 205.degree. C.

Crystalline isotactic poly(para-methylstyrene)

Fibers, such as wood fibers, are treated with a solvent solution of a thermoplastic polymer, e.g., polypropylene; the solvent is removed; and the treated fibers are fused into an article such as a fiber-polymer sheet or a board.

Method for preparing paperlike products from fibers threaded with polymer

Zeolite supported, organochromium based catalyst compositions are provided which are especially suitable for the polymerization of 1-olefins such as ethylene. Pi-bonded organochromium [II] compounds such as chromocene (dicyclopentadienyl chromium) are reacted with ZSM-5 type zeolites to produce such novel catalysts.

Catalyst for olefin polymerization

A polymer composition of polyparamethylstyrene and styrene-butadiene block copolymer. The polyparamethylstyrene has a molecular weight of about 50k-400k. The styrene-butadiene block copolymer has a weight average molecular weight of about 50k-250k, and is present in the composition in the amount of about 5-20 percent by weight as concentrated rubbery domains within the polyparamethylstyrene. Compositions according to the present invention show good impact, melt flow and transparency properties.

Impact polymer composition

A paper-polymer product as a fibrous, open web structure with polymer within the fiber structure of the cellulose fibers. The polymer is formed in-situ from a liquid, non-polar vinyl monomer such as p-chlorostyrene or p-methylstyrene. The open spaces of the fibrous web structure are substantially free from polymer.

Paper-polymer product

Rechargeable secondary battery comprising a cathode of a sheet loaded with graphite, an anode of a sheet containing high surface area carbon, and an electrolyte. The sheets can be prepared using a binder such as paper pulp and can be formed on paper making equipment.

Zeolite supported, organometallic derived catalyst compositions are provided which are especially suitable for the polymerization of 1-olefins such as ethylene. Organotitanium and organochromium compounds such as tributylchromium and tetrabutyltitanium are reacted with ZSM-5 type zeolites to produce such novel catalysts.

A blend, useful as a molding composition, of an unsaturated polyester with a mixture of isomeric methyl ethenyl benzenes containing a high proportion of the para-isomer.

Polyester resin blend

Zeolite supported, organometallic based catalyst composition are provided which are especially suitable for the polymerization of 1-olefins such as ethylene. Alkyltitanium and alkylchromium compounds such as tributylchromium and tetrabutyltitanium are reacted with ZSM-5 type zeolites to produce such novel catalysts.
