The present invention relates to a method for applying and using plant protection agents, preferably in agriculture and horticulture, in the form of sheets, webs and fabrics of organic material with integrated active substances. The integrated active substances slowly migrate from the polymer matrix and impose their effects at the point of application over an extended period of time. Such carrier/active substance combinations can be used as plant covers, mulches and for the production of stored crops.

Organic carrier with integrated active substances

The present invention relates to the stabilization of a carbonaceous combustible solid-diesel fuel suspension by inclusion therein of wax-like polymers in an amount of at least 0.2% by weight of the stabilized suspension. The polymers preferred are homopolymers of .alpha. -olefins, and copolymers of ethylene and at least one other monomer copolymerizable therewith wherein the ethylene portion constitutes at least 60% by weight of the copolymer.

Coal/diesel fuel suspensions containing wax-like polymers

The invention relates to a process for producing a magnesium-containing supported catalyst for the polymerization and copolymerization of .alpha.-olefins. The magnesium is bound via oxygen to a porous metal oxide; e.g. silicon dioxide and/or aluminum oxide, and has alkoxy groups. This solid is reacted with a transition metal compound and one or more organometallic compounds of Groups I to III of the Periodic Table are added.

A new catalyst for the homo- and copolymerization of .alpha.-olefins by a Ziegler type catalysis is described, the catalyst being prepared by reaction of a titanium (IV) compound with a carrier substance in the presence of a solution of at least about 0.1 weight percent of an atactic poly-.alpha.-olefin followed by reduction of the reaction product with an organoaluminum compound in an inert inorganic solvent and activation with an organoaluminum compound. The novel catalyst is useful in the preparation of extremely high molecular weight polyolefins of fine grained structures.

Process for the homo- and copolymerization of .alpha.-olefins

A catalyst for the polymerization of olefins is described wherein a titanium(IV) compound is reduced with an organoaluminum compound in the presence of atactic poly-.alpha.-olefin. Polymerization with the catalyst is also disclosed.
