The invention relates to novel composite materials comprising (a) an inorganic or organic bulk material having covalently bound to its surface initiator moieties for radical polymerization; and (b) a hydrophilic surface coating obtainable by applying one or more different ethylenically unsaturated hydrophilic macromonomers of formula (1) as outlined in the claims to the bulk material surface provided with the initiator radicals and polymerizing said macromonomers. The composite materials of the ...

An oral dosage form comprising fluvastatin and HPMC, which oral dosage form is color-stable upon prolonged periods of storage.

The present invention relates to novel crosslinkable amphiphilic block copolymers of formula ##STR1## wherein the variables are as defined in the claims, a process for their preparation and their use for the manufacture of mouldings. The block copolymers of the invention are especially useful for the manufacture of ophthalmic mouldings such as in particular contact lenses.

An organic photoconductor including a base layer formed of a first material and a photoconductive layer formed of a second material. The organic photoconductor being characterized in that when it is maintained in a curved orientation with the photoconductive layer facing outward, the photoconductive layer is subjected to less stress than the base layer. In one embodiment the first material is relatively more flexible and stretchable than said second material and the materials are pre-stressed in...

The disclosed invention relates to polyisocyanate based aerogels and their method of preparation. The aerogels are produced by mixing an organic polyisocyanate, carbon black and catalyst in a solvent. The invention advantageously enables preparation of filled polyisocyanate based organic aerogels of lower density than aerogels which do not include a filler.

This invention relates to novel benzospiran derivatives embraced by the formula ##STR1## wherein the sum of A and B is at least the integer 2; A is selected from the group consisting of --(CH.sub.2)--.sub.n wherein n is 1 through 5 and --(C.sub.n H.sub.2n -.sub.2 XY)-- wherein X is selected from the group consisting of hydroxy, acetoxy, amino and acetamido and Y is hydrogen, and X when taken together with Y is selected from the group consisting of =O and =CR.sup.3 R.sup.4 wherein R.sup.3 and R.s...

Particular, novel (dicarboxy)alkyl ethers are useful as builder ingredients in detergent compositions.

The amine salts of linear polyaniline compounds, including substituted polyaniline compounds, are useful, semiconductors. These materials are generally soluble in popular organic solvents and have resistivities between 10.sup.-.sup.3 and 10.sup.9 ohm-cm. These compounds are useful in the formation of semiconductor compositions, including self-supporting films, and various semiconductor elements such as antistatic films and fibers.

This invention provides compounds of formula I, ##STR1## wherein R.sub.1 is alkyl of 1 to 10 carbon atoms, cycloalkyl of 3 to 8 carbon atoms or phenyl, and R.sub.2 is hydrogen or alkyl of 1 to 4 carbon atoms, Useful as anti-phlogistics, anti-pyretics, analagesics and inhibitors of blood platelet aggregation.

Cyclopropyl substituted esters, syntheses thereof, compositions thereof, and use for the control of mites and ticks.
