  • Vinyl acetate/vinyl 3,5,5-trimethylhexanoate copolymer binder resins
    Patent number: 9315694
    Abstract: The present invention relates to a copolymer composition comprising 5-95 pphwm of vinyl acetate and 95-5 pphwm of vinyl 3,5,5-trimethylhexanoate, wherein the corresponding 3,5,5-trimethylhexanoic acid has a content of the 3,5,5-trimethylhexanoic acid isomer of at least 88% by weight. Said copolymer is composed and synthesized so as to be useful in the formulation of binders for fibrous substrates such as woven or nonwoven products, paints, adhesives for porous or non-porous substrates, construction cementitious compositions, redispersible powders.
    Type: Grant
    Filed: September 12, 2011
    Date of Patent: April 19, 2016
    Assignee: OXEA GMBH
    Inventors: Antonietta Schiro, Tito Zanetta, Christoph Balzarek, Olivier Borgmeier, Guido Frey, Leif Johnen, Donald Raff, Heinz Strutz

  • Process for lightening the color of polyol esters
    Publication number: 20110086997
    Abstract: The present invention relates to a process for lightening the color of polyol esters by reacting polyols with linear or branched aliphatic monocarboxylic acids having 3 to 20 carbon atoms, wherein the reaction product is worked up without using adsorbents and comprises a treatment with peroxidic compounds and an immediately subsequent steam treatment with subsequent drying.

  • Process for lightening the color of polyol esters
    Publication number: 20110087046
    Abstract: The present invention relates to a process for lightening the color of polyol esters by reacting polyols with linear or branched aliphatic monocarboxylic acids having 3 to 20 carbon atoms, wherein the reaction product is worked up without using adsorbents and comprises a treatment with ozone or ozone-containing gases and an immediately subsequent steam treatment with subsequent drying.
