Steven Rodberg 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).

  • Long chain polyether polyols
    Publication number: 20070149634
    Abstract: The present invention provides a long-chain polyether polyol having a number average molecular weight of greater than about 500 g/mole and produced by alkoxylating a polyoxyethylene-containing initiator with an alkylene oxide in the presence of a basic catalyst having at least one cation thereof chelated by the polyoxyethylene-containing initiator. The inventive long-chain polyether polyols may be used to provide flexible polyurethane foams and non-cellular polyurethanes.
    Type: Application

  • Base-catalyzed alkoxylation in the presence of non-linear polyoxyethylene-containing compounds
    Publication number: 20070149633
    Abstract: The present invention provides a long-chain polyether polyol having a number average molecular weight of greater than about 1,200 g/mole and produced by alkoxylating an initiator with an alkylene oxide in the presence of a basic catalyst having at least one cation thereof chelated with a non-linear polyoxyethylene-containing compound having a functionality of at least about three. The long-chain polyether polyols of the present invention may find use in providing flexible polyurethane foams and non-cellular polyurethanes.
