  • Patent number: 11498997
    Abstract: Process for the removal of volatile compounds from a tackifier comprising a resin with repeating units of formula I wherein R1 is a linear or branched alkylen group with 1 to 10 carbon atoms and R2 is a linear or branched, saturated or unsaturated N aliphatic hydrocarbon group with up to 20 carbon atoms, and optionally a plasticizer, wherein the tackifier is passed through at least one evaporator as film and the volatile compounds are removed from the film.
    Type: Grant

  • Patent number: 11447713
    Abstract: The invention relates to a method for the preparation of a hyperbranched polyester mixture obtainable by reacting a hydroxyl group containing carboxylic acid (B) with at least one carboxylic acid group and at least two hydroxyl groups with a diol (C) having a molecular weight of more than 100 g/mol, optionally in the presence of at least one further reactant, wherein the at least one further reactant is a polyol (A) having at least three hydroxyl groups under a reaction condition allowing ester and ether formation; and reacting the mixture resulting from step (a) with a hydrophobic carboxylic acid (D) resulting in the hyperbranched polyester mixture. The invention further relates to said hyperbranched polyester mixture and the use as wax inhibitor, as pour point depressant, as lubricant or in lubricating oils.

  • Patent number: 10316131
    Abstract: The invention relates to a hyperbranched polymer comprising: a) a hyperbranched polycondensate with hydroxyl end groups, amino end groups, or a combination thereof condensed to b) one or more linking groups connected to c1) one or more polyethylene glycol monomethyl ethers and c2) one or more poly(C2-C3)alkylene glycol mono-(C8-C22)-alkyl ethers, wherein the weight ratio of components c1):c2) is from 9:1 to 1:9. It further relates to a process for producing the polymer, to a composition comprising the polymer and an active ingredient, and to a method for controlling phytopathogenic fungi or undesired vegetation or insect or acarid infestations or for regulating the growth of plants.
