The formulation includes a compound A chosen from multifunctional cyclic carbonates of a formula (I) or a mixture thereof, a compound B chosen from multifunctional cyclic carbonates containing oxyalkylene groups &#x2014;OR3- of a formula (II) or a mixture thereof, a compound C chosen from multifunctional amines of a formula (III) or a mixture thereof and a compound D chosen from non-reactive blowing agents, as well as a process for preparing a non-isocyanate polyurethane foam, a foam obtainable by this process, compound B, a mixture of compounds A and B, the use of compound B for enhancing the solubility of a non-reactive blowing agent in a compound A and a foamable system having a first part A containing compound A and compound B and a second part B containing compound C, wherein part A and part B are preferably physically separated.

Non isocyanate polyurethane foams

The present invention relates to polyamide composites containing graphene, a method for producing them and to their use as or for producing a material with gas barrier and/or electroconductive and/or thermally conductive properties and/or a mechanically reinforced material.

Polyamide composites containing graphene

Process for producing a polymer-graphite nanocomposite, which comprises the steps

Polymer-graphite nanocomposites

The present invention relates to new catalyst supports comprising nanofibers, a catalyst system comprising these supports as well as a process for preparing nanocomposites and the nanocomposites prepared. The invention especially concerns a supported catalyst system for polymerization of olefins, comprising a support made of fibers or a fleece of fibers, wherein the mean fiber diameter is less than 1000 nm, preferably less than 500 nm and the mean fiber length is more than 200,000 nm, preferably more than 500,000 nm and especially preferred more than 1,000,000 nm as well as a process for polymerizing olefinic systems in the presence of these catalyst systems and the resulting nanocomposites.

Catalyst system for polymerization of olefinic monomers, process for preparing polymers, and polymers prepared by the process

Polymerizable materials which contain (1) 1 to 80 wt.-% of at least one polysiloxane, (2) 0.1 to 5 wt.-% of one or more initiators for radical polymerization, (3) 0 to 60 wt.-% of radically polymerizable monomer and (4) 1 to 50 wt.-% of one or more radically polymerizable monomers which carry at least phosphonic acid group, sulphonic acid group and/or mono- or dihydrogen phosphoric acid ester group, the polysiloxane (1), the monomer (3) or both being substituted by fluorine. The materials are suitable in particular for the coating of natural or artificial teeth.

Dental coating materials

A process for emulsion polymerizing one or more olefins involves reacting it/them with at least one complex compound of the formula Ia or b where M is a transition metal from groups 7 to 10 of the Periodic Table of the Elements and is preferably Ni in aqueous dispersion and at least one radical Rto Rand optionally one radical Rto Rcontains a hydrophilic group X, selection being made from &#x2014;SO, &#x2014;O&#x2014;PO, NH(R), N(R)or &#x2014;(OCHCH)OH, where n is an integer between 1 and 15. For the process of the invention it is optional to use an activator such as, for example, olefin complexes of rhodium or of nickel. This invention further relates to dispersions of polyolefins such as polyethylene and ethylene copolymers in water, for example, and to the use of the aqueous dispersions of the invention for paper applications such as paper coating or surface sizing, paints, adhesive base materials, molded foams such as mattresses, textile and leather applications, carpet back coatings, or pharmaceutical applications.

Method for the emulsion polymerization of olefins

A device and a process for producing three-dimensional objects is disclosed. The device has a container () for a medium () and a three-dimensionally positionable dispenser () for release of a material (), the addition of which to the medium () leads to the formation of solid structures, into the medium (). Addition of the material () by moving the dispenser in XYZ direction on a platform () below the filling height of the first material () in the container () leads to the formation of three-dimensional objects.
