  • Patent number: 11945940
    Abstract: A composition is provided comprising: a) polyvinylchloride, b) inorganic solid particles, and c) a polymer having a polyether segment, wherein at least 60 mol-% of the end groups of the polymer are selected from the group consisting of carboxylic acid groups and hydroxyl groups, and wherein at least a part of the end groups of the polymer is a carboxylic acid group, wherein the carboxylic acid end groups are linked to the polyether segment via a linking segment comprising an ester group.

  • Publication number: 20220267523
    Abstract: The invention relates to a polymer or oligomer comprising a) An oligomeric or polymeric core comprising carbon atoms and at least one of oxygen atoms and nitrogen atoms, and b) at least three hydrocarbyl terminal and/or pending groups having 12 to 100 carbon atoms, wherein the hydrocarbyl groups are linked to the core via c) a linking moiety comprising i) a urethane group and ii) a group selected from urethane group, urea group, and biuret group.

  • Patent number: 10253133
    Abstract: A reaction product containing urethane groups, comprising one or more species of the general formula (I) (R1—X)p—Z1—(XH)y??(I) where p+y=w and w is an integer from 2 to 10, p is an integer from 2 to 10, y is an integer from 0 to 8, and X is independently O, NH and/or NZ2 and XH is independently a hydroxyl group OH, a primary amino group NH2 and/or a secondary amino group NHZ2 where Z2 is independently a branched or unbranched, saturated or unsaturated organic radical G(U)a where U is independently a hydroxyl group, a primary amino group or a secondary amino group and a is an integer from 0 to 8, where w+a?10, G is a branched or unbranched, saturated or unsaturated organic radical, the p R1 radicals are independently a radical of the general formula (II) Y—O—CO—NH—R2—NH—CO??(II) in which the p Y radicals are independently a branched or unbranched, saturated or unsaturated organic radical which has 1 to 1000 carbon atoms and does not contain any hydroxyl groups, any primary amino groups or any secondary ami
