The invention relates to a composition for use in a Monosil process for the crosslinking of thermoplastic polyolefins which comprises The present invention further relates to production processes and to mouldings or, respectively, products obtained therefrom, based on thermoplastic polyolefins, where a composition of the invention is reacted together with at least one thermoplastic polyolefin in a Monosil process. The invention further relates to the use of a composition of the invention in the Monosil process for the crosslinking of thermoplastic polyolefins during the production of products moulded by means of extrusion, based on thermoplastic polyolefins.

Tin-free composition for crosslinking thermoplastic polyolefins

The invention relates to a composition of an organofunctional silane compound, particularly of a mono-unsaturated silane compound, and of an organic acid or a precursor compound which releases said organic acid, and to a method for the production of polymer compounds such as granulates and/or finished products from thermoplastic base polymers and/or monomers and/or prepolymers of the thermoplastic base polymer utilizing the composition, the organic acid, or the precursor compound which releases said organic acid. The invention also relates to the produced polymers, filled plastics such as, for example, granulates, finished products, molded bodies and/or articles such as pipes or cables. In addition, the invention relates to a kit containing the composition.

Silanol condensation catalysts for the cross-linking of filled and unfilled polymer compounds

The invention relates to a composition for use in a Monosil process for the crosslinking of thermoplastic polyolefins which comprises The present invention further relates to a production process, and also to moldings or products obtainable thereby based on thermoplastic polyolefins, where a composition of the invention is reacted together with at least one thermoplastic polyolefin in a Monosil process. The invention further relates to the use of a composition of the invention in the Monosil process for the crosslinking of thermoplastic polyolefins during the production of products molded by means of extrusion, based on thermoplastic polyolefins.

Tin-free catalyst-containing composition for a Monosil process with optimized process properties

Provided is a composite material which is in pellet form and which has particles with a core-shell structure, where the core of the particles has one or more magnetic materials, and the shell is made of silicon dioxide, and the pellet has one or more crosslinkable polyethylene and/or polyethylene-containing copolymers. Also provided is a process for crosslinking polyethylenes, by mixing the composite material, one or more free radical initiators, and at least one polyethylene, and heating the mixture inductively.

Composite material comprising polyethylene and magnetic particles

The invention relates to a composition containing olefinically functionalized siloxane oligomers which are derived from olefinically functionalized alkoxy silanes and optionally alkoxy silanes functionalized with saturated hydrocarbons and optionally a tetra alkoxysilane, at most comprising an olefinic group on the silicon atom and which has a reduced chloride content and a weight average molecular mass (Mw) of more than 315 g/mol.

Composition of olefinically functionalised siloxane oligomers based on alkoxy silanes

The invention relates to a composition of a carboxyl-functionalized silicon-containing precursor compound of at least two different organic acids, said composition having two, three, or four carboxyl groups functionalized with various hydrocarbon groups according to formula I and/or II. Said carboxyl groups can be released as carboxylic acids and can be used as silane hydrolysis catalysts and/or silane condensation catalysts. The invention further relates to methods for producing the composition, to the use of the composition for cross-linking polymers, and to a formulation of the composition in the form of a masterbatch.

Carboxyl-functionalized silicon-containing precursor compound of various organic carboxylic acids

A composition containing (i) at least one silicon-containing compound, (ii) at least one peroxidic free-radical initiator, and (iii) at least one conjugated hydrocarbon and/or at least one organofunctional silane of the general formula I:R&#x2014;X&#x2014;C(R)&#x2550;C(R)&#x2014;C(R)&#x2550;C(R)&#x2014;X&#x2014;Si(R)(OR)&#x2003;&#x2003;(I),may be used in the preparation of grafted and/or crosslinked polymers, or of filled plastics, in order to improve scorch performance. Processes for preparing polymers or preparing plastics, and polymers and plastics which are obtainable via the Sioplas process or via the Monosil process, and products produced from them can utilize the composition.
