  • Patent number: 7960496
    Abstract: Disclosed herein is a novel stabilizer for preparing a polymer polyol, which is used to prepare polyurethane foam having improved physical properties. The stabilizer is prepared by allowing maleic anhydride to react with a polyether polyol, having an OH functionality of 3-8 and a molecular weight of 3,000-15,000, and then adding ethylene oxide to the reaction solution. Because the molecular weight and functionality of the stabilizer are increased through aging and dimerization, the stabilizer has a high molecular weight of 5,000-30,000, a high OH functionality of 6-10 and a viscosity of 3,000-15,000 cps/25° C. A polymer polyol derived from the stabilizer has low viscosity compared to those of prior products and contributes to the improvement in the physical properties of the resulting polyurethane foam.

  • Patent number: 6884778
    Abstract: A new oligomer based on alternating fumaric acid and poly(ethylene glycol) (PEG) units is provided. The oligo(PEG fumarate) (OPF) may be functionalized by modification with a biocompatible organic group. Further, the OPF may be cross-linked using radical polymerization in the presence of either a chemical or photo initiator. A cross-linked OPF gel has a swelling behavior that is tunable dependent on the molecular weight of PEG. A cross-linkable PEG macromer, as exemplified by oligo(PEG fumarate), has unsaturated double bonds, for example in the fumaryl groups, along its macromolecular chain that allows for the preparation of hydrogels with tailored structure and properties.
