  • Patent number: 11512192
    Abstract: The invention relates to a composition comprising a) a thermoplastic matrix polymer based on one or more ethylenically unsaturated polymerizable monomer(s), wherein the thermoplastic polymer is selected from the group consisting of polyolefins, polystyrene, polyacrylates, ethylene-vinylacetate copolymer, and copolymers and blends of the aforementioned, b) an inorganic flame retardant, c) a polymer based on one or more ethylenically unsaturated polymerizable monomers and having a plurality of alkoxysilane and/or acetoxysilane groups covalently linked to the polymer, wherein the ethylenically unsaturated polymerizable monomers of component c) are different or have a different composition than the ethylenically unsaturated monomer(s) of component a) and d) a clay.

  • Patent number: 11015026
    Abstract: The invention relates to polyesters of the following general formula, wherein the residues R1, R2, R3, R4, R5a (as a special case of residue R5), R6, R7 and R8 are free of carboxy, hydroxy, thiol, imino, and primary and secondary amino groups, the residues R5b (as a special case of R5) and R9 contain hydroxyl groups, 10 to 100 mol % of which can be present in salt form analogously to polymers or otherwise capped, u=0 or 1, v=1 to 60 and w=1 to 20. The invention further relates to wetting agents and dispersants that contain the aforementioned polyesters or consist thereof and to a method for producing said wetting agents and dispersants, to the use of the polyesters and reaction products of the method according to the invention as wetting agents and dispersants, and to compositions containing the polyesters, wetting agents and/or dispersants or reaction products of the method according to the invention and particulate solids.
