But you can also first the hydroxyl-containing esters of unsaturated React carboxylic acids with the monomeric aromatic vinyl compounds and these Compounds then form the corresponding urethanes through the action of isocyanates convert. Among the hydroxyl-containing esters made from polyalcohols and unsaturated Carboxylic acids that can be used as starting materials for the present process, are in particular those by transesterification of natural unsaturated oils, such as z. B. linseed oil, wood oil, castor oil and oiticica oil with polyalcohols, such as. B. glycerine, Pentaerythritol or trimethylolethane, called available mono- or diesters, furthermore hydroxyl-containing esters of this type of the alkyd resin type, d. H. so those in which the residues of polybasic carboxylic acids, such as. B. phthalic acid, succinic acid, Adipic acid or maleic acid.
Als Isocyanate eignen sich für das vorliegende Verfahren z. B. Phenylisocyanat, Dichlorphenylisocyanat, Cyclohexylisocyanat, das Isocyanat aus dem Palmfettamingemisch, ß-Dekalylisocyanat, i-Chlorphenylen -2, 4-diisocyanat, Toluylendiisocyanat und 1, 6-Hexämethylendiisocyanat. Statt der Isocyanate kann man auch Stoffe anwenden, die wie diese reagieren: so z. B. Urethane oder Additionsprodukte aus Isocyanaten und Verbindungen, die aktiven -Wasserstoff enthalten, die unter den Umsetzungsbedingungen unter Bildung von Isocyanat spaltbar sind, so z. B. die Additionsprodukte aus Isocyanaten und Acetessigester oder Malonester.As isocyanates are suitable for the present process, for.

Instead of isocyanates, you can also use substances who react like this: B. urethanes or addition products of isocyanates and compounds containing active hydrogen, which under the reaction conditions are cleavable with the formation of isocyanate, e.g. B. the addition products of isocyanates and acetoacetic ester or malonic ester.
