Abstract
Novel monomers are described which contain a glucaric acid unit linked through an amide bond formed between a carbonyl carbon of a D-glucaric acid and one of the amino nitrogens of a primary diamine as well as their alkali metal salts. These N-aminohydrocarbylene (or N-aminoheterohydrocarbylene)-D-glucaramidates may then be polymerized to form polyhydroxypolyamides and in particular stereoregular polyhydroxypolyamides.
