A process for producing an aromatic polycarbonate in a water-in-oil emulsified form, having an improved heat stability during molding at a high temperature, is described. In the process according to the present invention, a tertiary amine is added to the water-to-oil emulsion after the average diameter of liquid droplets of the water phase is reduced to not more than 10.mu.m. The polycarbonate obtained by the process of the present invention is improved in heat stability and can provide a molded article with less coloration.

Water-in-oil emulsion process for producing an aromatic polycarbonate

A copolyamide resin containing a dimerized fatty acid as a copolymer component, which has (1) at least 25 equivalent %, based on the total number of terminal groups, of hydrocarbon groups having from 6 to 22 carbon atoms at its terminals, (2) a content of a dimerized fatty acid of from 0.1 to 40% by weight based on the total amount of the resin, and (3) a melt viscosity as measured at 240.degree. C. of from 2,000 to 15,000 poise.

Polyamide resin

Disclosed herein is a resin composition comprising

Aromatic polyester/aromatic polycarbonate/alpha-olefin unsaturated

Disclosed herein is a polyamide resin composition comprising a polyamide resin, from 0.1 to 1% by weight of fine silica based on the polyamide resin and from 1 to 99% by weight of a silane coupling agent based on the fine silica. The packaging material obtained from the polyamide resin composition of the present invention has uniform and satisfactory transparency and is excellent in the blocking resistance.

Polyamide resin composition

The present invention relates to a process for preparing a 2-(1-hydroxyalkyl)cyclohexanone and/or a 2-alkylidene cyclohexanone. According to the present invention, the reaction of cyclohexanone with an aliphatic aldehyde is conducted in a heterogeneous system of an oil-in-water emulsion, whereby it is possible to obtain the 2-(1-hydroxyalkyl)cyclohexanone and/or the 2-alkylidene cyclohexanone in high selectivity.

Process for preparing 2-(1-hydroxyalkyl) cyclohexanone and/or

A process for preparing 2,3-dihydro-7-aminobenzofurans by reaction between 2,3-dihydro-7-halobenzofurans and ammonia in the presence of a copper catalyst, is described. The 2,3-dihydro-7-aminobenzofurans are useful as intermediates for insecticides.
