  • Wetting agents and dispersants based on mixtures of structure copolymers
    Patent number: 8871856
    Abstract: The invention relates to compositions comprising two structured linear copolymers selected from the group consisting of block copolymers and gradient copolymers, these copolymers being prepared by different controlled polymerization techniques and the difference in the polydispersities of these copolymers, ?(Mw/Mn), being ?0.25. The invention further relates to the production of such blends and to their use as wetting agents and dispersants.

  • Curable Polymer Mixture
    Publication number: 20130289195
    Abstract: The invention relates to a composite formulation comprising a specific mediator additive component (A) of relatively high molecular weight, a filler component (B) and a binder component (C). The composite formulation can be cured to a composite which is especially suitable for the production of moldings.

  • Stabilized unsaturated polyester resin mixtures
    Patent number: 7582701
    Abstract: The invention relates to an unsaturated polyester resin mixture which can be cured by applying external pressure and which encompasses at least the following components: a) an unsaturated polyester resin whose weight-average molar mass is from 500 to 5000 g/mol; b) an ethylenically unsaturated monomer; c) a shrinkage-reducing component; d) an inert filler; and e) a reinforcing fibre; and f) from 0.01 to 1% by weight of a block copolymer, based on the total weight of the unsaturated polyester resin mixture comprising reinforcing fibre, where the block copolymer encompasses at least one A block and encompasses at least one B block, where the A block contains at least one amine-containing, ethylenically unsaturated monomer; and the B block contains at least one alkyl- and/or phenyl-containing, ethylenically unsaturated monomer, and is free from amine-containing, ethylenically unsaturated monomers.
