Abstract: Polycarbonates formed at least in part from dihydroxy aryl ketones and optionally benzylic hydrogen containing aromatic diols may be crosslinked by exposure to electromagnetic radiation such as ultraviolet light, thereby imparting improved solvent resistance.

Abstract: An optical memory storage media is described, e.g. a compact disc. A method of preparing the media (e.g. discs) is also taught. The storage media is formed from a substrate material having tightly bonded to the surface a highly reflective soft metal alloy formed of, for example, an alloy including at least five percent by weight of each of at least two metals selected from the group consisting of cadmium, indium, tin, antimony, lead, bismuth, magnesium, copper, aluminum, zinc and silver.

Abstract: A process to form silyl ethers by contacting a carbonyl compound with an organosilicon hydride under reaction conditions in the presence of a catalyst, said catalyst being formed from a transition metal carbonyl coordination compound precursor by irradiation at an appropriate wavelength.

Abstract: Polyether hydroxyl-containing compounds are prepared by reacting a monoepoxy-containing compound such as propylene oxide with a compound containing one or more OH and/or SH groups such as a low molecular weight adduct of glycerine and propylene oxide in the presence of a solid calcium naphthenate catalyst. The solid form of the catalyst is more efficient than the liquid form.
