Abstract
A plasticizer capable of fast gelling and capable of imparting storage stability on plastisols contains dialkyl terephthalate, wherein the alkyl radicals of said dialkyl terephthalate have a longest carbon chain of at least 4 carbon atoms and have a total number of carbon atoms per alkyl radical of 5.
Claims28
A plasticizer, comprising:
- dialkyl terephthalate,
- wherein the alkyl radicals of said dialkyl terephthalate have a longest carbon chain of at least 4 carbon atoms and have a total number of carbon atoms per alkyl radical of 5.
A composition, comprising:
- a dialkyl terephthalate, and
- a polymer selected from the group consisting of PVC, PVB, PAMA, homopolymers or copolymers based on ethylene, propylene, butadiene, vinyl acetate, glycidyl acrylate, glycidyl methacrylate, methacrylates, acrylates, acrylates or methacrylates in which attached to the oxygen atom of the ester group there are alkyl radicals of branched or unbranched alcohols having from one to ten carbon atoms, styrene, acrylonitrile, cyclic olefins and mixtures thereof,
- wherein the alkyl radicals of the dialkyl terephthalate have a longest carbon chain of at least 4 carbon atoms and have a total number of carbon atoms per alkyl radical of from 4 to 5.
A process for preparing a dialkyl terephthalate, comprising
- a) hydroformylating C3 or C4 olefins to give C4 or C5 aldehydes, respectively,
- b) hydrogenating the aldehydes obtained in step a) to the corresponding alcohols, and
- c) reacting the alcohols from b) with terephthalic acid or with a derivative of terephthalic acid to the corresponding diester,
- wherein said dialkyl terephthalate has alkyl radicals which have a longest carbon chain of at least 4 carbon atoms and have a total number of carbon atoms per alkyl radical of from 4 to 5.
