Abstract: Nonionic substances which form disk-shaped micelles in aqueous solution and are of the formula (I) where R is H or R1 is C1-C4alkyl, R2 is H or CH3, x is from 3 to 12 and y is from 3 to 15, and polymers of compounds of the formula I where R is processes for the preparation of the compounds of the formula I and of the polymers, and the use of the compounds described as additives to detergents and cleaning agents, for other surfactant applications and as liquid crystals for optical, electronic and optoelectronic applications.

Abstract: Polymer surfactants based on copolymers of (a) hydrophobic monomers of (meth)acrylic esters ((meth)acrylates) and (b) hydrophilic monomers of (meth)acrylic esters. The copolymers form liquid crystalline phases in the binary system with water and are used as additives for detergents.

Abstract: The membranes comprise synthetic polymers which have liquid-crystalline phases and whose mesogenic groups are bonded in the chain of the polymer or as side chain to the polymer. By comparison with polymer membranes which contain liquid-crystalline, low-molecular-weight compounds, the membranes of the invention comprise a one-phase system whose composition remains constant. A further advantage is that the liquid-crystalline phases can be aligned, giving improved permeability.
