Abstract
1. Polyamides and polyamide-esters were synthesized by the reaction of bisoxazolinones with diamines, diols, and amino alcohols. 2. Polyamides of regular structure formed by reaction of bisoxazolinones with diamines have higher melting points than polyamides with a random distribution of monomer residues, such as are obtained by direct polycondensation. 3. In the case of the polymers of regular structure, replacement of the octamethylene group by the phenylene group leads to greater rise in melting point than in the case of the polymers having macromolecules of irregular structure.
