  • Patent number: 9249264
    Abstract: A hybrid film-forming composition is prepared by forming an aqueous mixture including an organofunctional silane, a metal chloride, and an acid, and boiling the mixture. A base is added to the aqueous mixture to substantially neutralize the mixture and to form a hydroxide of the metal. A colloidal suspension including the metal hydroxide and a siloxy compound is formed. A peroxide-based solution is added to the suspension to form a suspension including a peroxide of the metal. The suspension is allowed to equilibrate at room temperature. The suspension is boiled at a pressure greater than atmospheric pressure to form a hybrid film-forming composition including the condensation product of a siloxy compound and a metal peroxide. A coating formed from the hybrid film-forming composition may be hydrophobic or hydrophilic.

  • Patent number: 9242909
    Abstract: A first method for refining dicyclopentadiene of the present invention is characterized in that the method separates and recovers dicyclopentadiene by distilling the crude dicyclopentadiene that contains dicyclopentadiene and is obtained by removing a C5 fraction and a BTX fraction from the reaction product obtained by dimerization reaction of the cracked gasoline by-produced in an ethylene plant that uses as feed stock a C2 fraction, a C3 fraction and a C4 fraction. A second method for refining dicyclopentadiene of the present invention is characterized in that the dicyclopentadiene-containing fraction refined by distillation is brought into contact with an inert gas or a hydrocarbon gas having 1 to 3 carbon atoms.

  • Patent number: 5428068
    Abstract: This invention relates to a thermosetting unsaturated polyester or vinyl ester resin compositions modified with AB or ABA block copolymers. The A blocks are unsaturated polyester while the B blocks are flexible poller having a Tg of 0.degree. C. or lower. The blocks are generally separately prepared having a variety of terminal groups such as hydroxyl, carboxyl, amine, or isocyanate groups, but low molecular weight A blocks can be prepared in situ on the B blocks, The functionality of the blocks can be controlled to get AB or ABA diblocks and polyblocks, These modified unsaturated polyester or vinyl ester resin compositions have higher flexural strain to failure and are generally tougher than standard resins without modification. Control of the reaction conditions and the functionality of the blocks prior to coupling minimizes the formation of A(BA).sub.n where n is an integer above 1.

  • Patent number: 5399611
    Abstract: This invention relates to novel hydroxy-functional polyester diluents, and more particularly, to acrylic-modified hydroxy-functional polyester reactive diluents useful for blending with a variety of thermosetting or thermoplastic film-forming polymers. More specifically, the hydroxy-functional polyester reactive diluents are essentially low molecular weight polyesters derived from triols, and a combination of unsaturated monocarboxylic acids and saturated monocarboxylic acids. These hydroxy-functional polyester diluents may be copolymerized with one or more acrylic monomers, i.e. hydroxy-functional acrylic monomers, and blended with a variety of thermosetting or thermoplastic film-forming polymers. These blends of the film-forming polymers and the hydroxy-functional polyester diluents can be crosslinked with conventional crosslinking agents such as isocyanates and used in the formulation of low VOC paint compositions particularly useful as automotive topcoats.

  • Patent number: 5326516
    Abstract: This invention relates to a process for preparing a pigmented thermoplastic polymer composition which is useful as a low profile additive composition for thermosetting resins. The process includes the steps of(A) selecting at least on thermoplastic polymer having a refractive index which is within about 0.06 units of the refractive index of the thermosetting resin;(B) preparing a mixture of said thermoplastic polymer and at least one color pigment, dye or mixture thereof under high shear in a high-intensity mixer; and(C) forming a slurry containing said mixture obtained in step (B) in at least one liquid copolymerizable monomer containing at least one CH.sub.2 .dbd.C<group. In a preferred embodiment, at least one surfactant is included in the slurry obtained in step (C) in an amount sufficient to enhance the uniformity of the pigmentation of a cured composite produced from the thermosetting resin composition and a low profile additive composition.

  • Patent number: 5254642
    Abstract: The present invention is based on the unexpected discovery that the low profile additives (LPA) disclosed in U.S. Pat. No. 5,116,917 provide effective shrinkage control when used with various blends of vinyl ester and polyester resin systems. This LPA is unique in that its low profile efficiency is not affected by the different reactivities displayed by blends of vinyl ester resin and polyester resin at different blend ratios. This LPA is equally effective in formulations of all vinyl ester resin, all polyester resin, or any combination of such two resins. The present invention, then, is directed to a thermosettable resinous composition of between about 0 and 95 wt-% of a thermosettable vinyl ester resin; between about 5 and 100 wt-% of a thermosettable polyester resin; and between about 5 and 40 wt-% of a low profile additive comprising a non-gelling, saturated polyester formed from dibasic acid and an EO/PO block copolymer having an EO/PO molar ratio ranging from about 0.1 to 0.

  • Patent number: 5002983
    Abstract: A polyarylene sulfide resin composition comprising a composition obtainable by a reaction of a polymer composition comprising(A) 100 parts by weight of a polyarylene sulfide resin,(B) 0.1 to 40 parts by weight of a monomer having one or more ethylenic unsaturated bonds and(C) 0 to 40 parts by weight of an unsaturated polyester. In the polyarylene sulfide resin composition of the present invention, a polymer produced by polymerization of the monomer or the monomer and unsaturated polyester, as compared with a resin composition wherein said polymer is simply blended, is in a state wherein it is uniformly mixed with the polyarylene sulfide resin and if necessary a filler. In other words, said polymer is uniformly dispersed in and mixed with the polyarylene sulfide resin to such a degree that the composition shows no phase separation even if it is passed through molding processes such as extrusion molding, injection molding, etc. carried out under normal conditions.
