Abstract: This invention provides a novel anti-microbial system suitable for formulation in a wide variety of ophthalmic solutions. In particular the composition comprises an antimicrobial peptide that is an indolicidin and a buffer compatible with application to a mammalian eye, wherein the buffer is a Good's buffer or the buffer has a halide ion concentration less than 0.85 wt %. The compositions are useful for storing, cleaning, or disinfecting a contact lens. In particular the compositions are self-preserving upon lengthy storage, effective in cleaning and sterilizing contact lenses upon exposure of the lens to the composition, do not require the need for physical or thermal treatment of the lens and enable the immediate application of the lens to the eye without the need for neutralization, deactivation or washing.

Abstract: Multilayer structures comprising at least a fluorinated thermoplastic and a non-fluorinated thermoplastic wherein the adhesive intermediate layer comprises a fluorinated thermoplastic, a non-fluorinated thermoplastic and an ionomer which comprises copolymers having reactive groups salified or not; the amount of reactive groups in the ionomer copolymer being preferably higher than 3% by weight, in general between 8-35%.

Abstract: An aromatic polyesteramide possessing thermotropic liquid crystalline polymer characteristics, which are easily workable in the molten state and have the mesogenic group in the main chain, are obtained by condensing possible substituted aminophenols and hydroquinone derivatives with aromatic dicarboxylic acids.

Abstract: A process for the synthesis of phenyl substituted aromatic diols, obtained by dehydrogenation of the corresponding substituted cyclohexyl derivatives in the presence of a palladium supported catalyst, said palladium supported catalyst being prepared by a process which comprises treating a palladium hydrolysis compound with reducing agents.

Abstract: Polymers obtained from the polycondensation of at least one di-s-triazine of the formula: ##STR1## wherein: R represents a linear or branched alkyl radical containing from 1 to 5 carbon atoms,X represents a halogen, andn is an integer within the range of from 5 to 30, with at least one other copolymerizable monomer, capable of yielding a liquid-crystalline, thermotropic polymer.

Abstract: Thermotropic liquid crystalline aromatic polyesters of 4,4'-dihydroxydiphenyl substituted in 3,3' positions by a halogen or by an alkyl, cycloalkyl or aralkyl radical.
