摘要:
Polyacrylate esters with long-chain hydrocarbon and polyoxyalkylene groups are disclosed, which are prepared by transesterification of polyacrylate alkyl esters, the alkyl groups of which have 1 to 4 carbon atoms and which were obtained by free radical polymerization, wherein the transesterification is carried out with a mixture of selected alcohols and polyoxyalkylene monools. Compared to products obtained by copolymerization, the transesterification products are largely free of undesirable low molecular weight components, have a narrow molecular weight distribution and exhibit excellent surfactant properties. They are useful especially as W/O emulsifiers for natural and synthetic oils.
摘要:
Polyacrylate esters with quaternary ammonium groups are disclosed. The esters are obtained by transesterifying alkyl polyacrylate esters with a mixture of dialkylaminoalkanols and saturated or unsaturated aliphatic alcohols with 8 to 22 carbon atoms, followed by quaternization.The polymers are free of physiologically questionable components and can therefore be used for the preparation of cosmetic products, preferably for hair cosmetics. The polymers furthermore are suitable for finishing fibers or of textile products.The invention is furthermore directed to polyacrylate esters with tertiary amino groups, which are formed as intermediates in the preparation of polyacrylate esters with quaternary ammonium groups.
