Process for the preparation of 3-substituted thiophenes

The invention concerns a polymer support of with highly accessible reactive groups onto which desired functional groups or metals can be attached, the polymer support comprising a polymer material which is grafted with reactive groups suitable to bind the functional group or metal to be loaded. The polymer material is encompassed in a bag made of meshed fabric which is tight enough to essentially prevent the escape of the polymer material from the bag. Furthermore, the invention relates to a functionalized polymer support and to a process for its preparation. The invention also concerns a product useful as an intermediate in the preparation of the polymer support.

Polymer supports comprising highly reactive grafted polyolefin

The object of the present invention is a process of preparation of a graft copolymer obtained by pre-irradiation grafting of vinyl monomers onto polyolefins or fluorinated polyethylenes, in particular, of grafting acrylic or methacrylic acid onto polyethylene and/or polypropylene and subsequently loading a metal, such as a transition metal on the graft copolymer obtained. Such metal-loaded graft copolymers find use, especially as catalysts, e.g. for hydrogenation reactions.
