Abstract: This invention relates to an optical resolving agent containing cellulose acetate of the II type and provides an optical resolving agent which exhibits an excellent power of resolving various isomers, in particular, optical isomers which have been difficult to resolve. The cellulose triacetate of type II used in the invention can be either relatively highly crystalline or relatively non-crystalline (amorphous).

Abstract: A polymer composition comprises (I) from 5 to 95 wt.% of a polyester resin having as the acid component terephthalic acid or an ester thereof and as the glycol component from 1 to 25 mole% of a glycol having the formula (I) as given below and from 99 to 75 mole% of tetramethylene glycol, and (II) from 95 to 5 wt.% of a polycarbonate of a di- (monohydroxyphenyl)-substituted aliphatic hydrocarbon. The formula (1) of the glycol is: in which R1 and R2 are each hydrogen or an alkyl group having 1 to 4 carbon atoms, provided that R1 and R2 are not hydrogen at the same time.
