Patent number: 5830943Abstract: The invention relates to a process for the preparation of a modified polymer by reaction between a reactive polymer and at least a compound containing two or more functional groups. The polymer, which is solid at room temperature, is mixed, at a temperature at which the viscosity of the polymer is lower than 10000 dPas (measured according to Emila), with a compound containing two or more functional groups in a mixing means for achieving a homogeneous product and the mean residence time and the residence time distribution being chosen so that more than 50% of the reactive groups of the polymer has reacted.As means to make the composition homogeneous use is made of a static mixer.The functional groups of the compound containing two or more functional groups have different reactivities.The invention also relates to a binder composition, which comprises the modified polymer thus obtained and a crosslinker.Type: GrantFiled: July 23, 1996Date of Patent: November 3, 1998Assignee: DSM N.V.Inventor: Dirk A. W. Stanssens

Patent number: 5821296Abstract: The present invention is drawn to a polyurethane-polyester hybrid resin system wherein the components of the system have improved shelf life stability. The resin system comprises an A-Side comprising a multifunctional isocyanate and a free radical initiator. The hybrid resin system also comprises a B-Side comprising a hydroxyl-terminated unsaturated polyester polyol, an ethylenically unsaturated monomer, a polyurethane catalyst, a polymerization inhibitor, and optionally a peroxide promoter, chain extender and filler. The B-Side polymerization inhibitor of the present invention comprises substituted hindered phenol-type compounds with ring substituents producing activated benzylic hydrogens, nitrophenols with or without benzylic-type substituents, naphthoquinones, stabilized radical compounds, and mixtures thereof.Type: GrantFiled: April 22, 1996Date of Patent: October 13, 1998Assignee: Aristech Chemical CorporationInventor: Keith A. Borden

Patent number: 5773531Abstract: A modified acrylic urethane prepolymer composition and an unsaturated polyester resin composition to which the prepolymer has been added. The prepolymer composition includes an acrylic urethane prepolymer prepared by the reaction of diisocyanate, like MDI, with an hydroxyl-containing acrylate monomer, such as a pentaerythritol triacrylate, which prepolymer composition may contain a styrene monomer and an inhibitor, such as benzoquinone, to retard the reaction of the prepolymer and styrene monomer prior to the addition of the prepolymer composition into the polyester resin composition. The employment of the modified urethane prepolymer composition provides for the reduction in the amount of styrene monomer used in the unsaturated resin composition and also provides for improved chemical and physical properties of the cured, unsaturated resin composition, such as a reduction in glass roll-out when the resin composition is employed with fiberglass.Type: GrantFiled: August 29, 1997Date of Patent: June 30, 1998Assignee: Hehr International Inc.Inventor: Stuart B. Smith

Patent number: 5741851Abstract: There is a provided a stable low viscosity graft polymer dispersion comprising from 25 to 60 weight percent based on the total weight of the polymer dispersion of at least three ethylenically unsaturated monomers polymerized in the presence of a reaction moderator and a free radical initiator in a polyol mixture initially containing less than 0.1 moles of induced unsaturation per mole of said polyol mixture. One of the monomers in the mixture of ethylenically unsaturated monomers is a hydroxylfunctional or aminofunctional C.sub.2 -C.sub.6 alkyl methacrylate.Type: GrantFiled: August 30, 1995Date of Patent: April 21, 1998Assignee: BASF CorporationInventors: Duane A. Heyman, James A. Gallagher
