A precision product container of the present invention comprises a resin composition as a base material, which comprises a polycarbonate resin and an epoxy compound. Such precision product container can remarkably prevent products contained therein from being contaminated by chlorine and is suitable as a container for a precision product which is free from operational errors of the precision product contained therein when this product is subsequently assembled or processed.

Precision product container

A method for producing a block copolyamide, which comprises polycondensing a prepolymer prepared from a dimerized fatty acid and a diamine and having a number average molecular weight of from 1,000 to 50,000, with a polyamide material other than said prepolymer component or a prepolymer thereof.

Method for producing a block copolyamide

Disclosed herein is a process for producing a polyamide comprising polymerizing at least one monomer of polyamide in the presence of

Process for producing polyamide

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 are a polyamide resin of a relative viscosity of from 2.5 to 6, having hydrocarbon group(s) of 6 to 22 carbon atoms as the end group(s) thereof, the number of the hydrocarbon group(s) being 40 to 100% of the total number of the end groups of the polyamide, and a process for producing the polyamide resin.
