    摘要: Thermally stabilized compositions of halogen-containing resins may be obtained by addition to the resin of a stabilizing agent of N.sup..omega.-higher alkyl or higher aliphatic acyl basic amino acid chelates of divalent metals or a mixture of or precursory ingredients thereof which is capable of forming N.sup..omega.-higher alkyl or higher aliphatic acyl-basic amino acid chelates when heated at the usual processing temperature of the halogen-containing resin.

    摘要: An improved process for the production of 5-amino-1,2,4-thiadiazol-3-yl-(2-(lower)-alkoxyimino)acetic acids starting from 5-substituted- or unsubstituted-3-amino-isoxazole compounds is disclosed herein. The title compounds are useful as acylating agents for the production of 7-acylaminocephalosporins.
