Richard A. Budnik 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).

  • Polyethers and polysiloxane copolymers manufactured with double metal cyanide catalysts
    Patent number: 5877268
    Abstract: The invention discloses a new class of silicone surfactants and their use for the preparation of flexible urethane foam. The surfactants incorporate high molecular weight polyethers prepared with narrower molecular weight distributions than conventional polyethers. These polyethers are prepared using a double metal cyanide (DMC) catalyst. These surfactants are better foam stabilizers than the analogous surfactants prepared from conventional polyethers.
    Type: Grant
    Filed: October 13, 1998
    Date of Patent: March 2, 1999
    Assignee: OSi Specialties, Inc.

  • Surfactants for manufacture of urethane foams
    Patent number: 5145879
    Abstract: Silicone surfactants having a siloxane backbone and a mixture of high and low atomic mass oxyalkylene pendant groups, these polyether pendants having average atomic masses of 1500-6000 and 300-750 respectively. The surfactants of the invention operate in polyurethane foam compositions to provide stable foams over a range of surfactant concentrations while still producing product foams having relatively constant breathability. Also disclosed and claimed are polyurethane foam compositions which include the surfactants, a method of making polyurethane foam using the surfactants, and polyurethane foam made by the method.

  • Processes for preparing silicone surfactants containing cyclic siloxane pendants, and polyurethane foam using such surfactants
    Patent number: 5041468
    Abstract: Novel siloxane-polyether polymers are provided containing cyclic siloxanes which are useful in silicone surfactants for foam polyurethane foam applications. The novel polymers are prepared by reacting a polyhydridosiloxane polymer with a cyclic polysiloxane containing a vinyl group and with an allyl started polyoxyalkylene polymer in the presence of a platinum catalyst. The resulting polymeric products are highly potent and impart flat breathability profiles to foams when used as surfactants in their preparation.
