Mats J. Sundell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polymer supports comprising highly reactive grafted polyolefin inescapably enclosed within a mesh fabric bag
    Patent number: 5415908
    Abstract: 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.

  • Process for the preparation of a graft copolymer bound catalyst
    Patent number: 5326825
    Abstract: 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.

  • Process for making a macroporous styrene polymer
    Patent number: 5300604
    Abstract: The invention relates to novel methylene bisphosphonic acid derivatives carrying a styrene group attached to the methylene carbon. The novel compounds are useful e.g. for functionalizing polymers of styrene type, especially macroporous styrene polymers, by copolymerizing the novel derivative with styrene and optional crosslinking agents. The invention also provides for new crosslinking agents especially suitable for the said purpose.
