  • CONTINUOUS PROCESS FOR THE PREPARATION OF A REACTIVE POLYMER
    Publication number: 20080207838
    Abstract: A continuous process for the reactive compatibilization of polymers includes I. processing monooxazoline, bisoxazoline or a mixture thereof together with a first polymer, to give a reactive polymer; and II. adding the reactive polymer to one or more second polymers. In addition, a reactive polymer contains I. a first polymer; and II. at least 5% by weight of chemically unbound monooxazoline, bisoxazoline or a mixture thereof.

  • Color stabilization of base-stabilized ethylenically modified unsaturated monomers
    Patent number: 7002035
    Abstract: The invention relates to the use of at least one compound from the tocopherol group for the color stabilization of ethylenically unsaturated monomers, particularly hydroxyalkyl(meth)acrylates, which already comprise at least one polymerization inhibitor for base stabilization or storage stabilization. Such color-stabilized and polymerization-inhibited monomers are preferably used in clearcoat and high solid paints.
