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.
Claims7
A process for preparing a stereoregular head, tail-poly(glucaramide) which comprises mixing a salt selected from the group consisting of N-aminohydrocarbyleneglucaramidate salts derived from a symmetrical diamine and N-aminoheterohydrocarbyleneglucaramidate salts derived from a symmetrical diamine with an alkanol selected from the group consisting of methanol, ethanol, propanol and isopropanol containing a strong acid and then basifying the resulting mixture to form the poly(glucaramide).
A process for preparing poly(glucaramides) which comprises reacting mixing at least one salt selected from the group consisting of N-aminohydrocarbyleneglucaramidate salts and N-aminoheterohydrocarbyleneglucaramidate salts with an alkanol selected from the group consisting of methanol, ethanol, propanol and isopropanol containing a strong acid and then basifying the resulting mixture to form the poly(glucaramide).
Stereoregular head, tail-poly(hydrocarbyleneglucaramides) and stereoregular head, tail poly(heterohydrocarbyleneglucaramides).
