Claims
- 1. A process of forming polymers of Formula I below containing hydroxylmaleimide repeat units: ##STR4## where R, R.sub.1, R.sub.2 and R.sub.3 are selected from H, alkyl, alkoxy, cycloalkyl, aryl, ester, carboxy, hydroxy, hydroxyalkyl, amido, fluoro, halogen and silyl; and
- R.sub.4 is H or alkyl;
- R' is derived from a hydroxy-containing .alpha.-unsubstituted primary amine wherein R' also including a group derived from an .alpha.-unsubstituted primary amine having one or more of the following groups therein: hydrogen, aryl, alkyl, heterocyclic, aromatic, fluoro, silyl, amino, olefinic, carboxy and halogen; and
- x is 0-0.95, y=0-0.90 and z=0.05-1.00;
- which comprises reacting: ##STR5## in aqueous or aqueous-alcoholic solution, where R, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as defined above, with a hydroxy-containing .alpha.-unsubstituted primary amine, R'NH.sub.2, where R' is as defined above, at a temperature of about 60.degree.-160.degree. C., for a reaction period of about 1-25 hours.
- 2. A process according to claim 1 wherein the reaction temperature is about 80.degree.-150.degree. C.
- 3. A process according to claim 1 wherein the reaction temperature is about 100.degree.-130.degree. C.
- 4. A process according to claim 1 wherein the reaction time is about 1-25 hours.
- 5. A process according to claim 1 wherein the reaction time is about 2-10 hours.
- 6. A process according to claim 1 wherein R' is synthesized by reaction with ethanolamine.
- 7. A process according to claim 1 wherein R' is synthesized by reaction with 3-amino-1-propanol.
- 8. A process according to claim 1 wherein R is alkyl and R.sub.1, R.sub.2 and R.sub.3 are H.
- 9. A process according to claim 1 wherein R and R.sub.1 are alkyl and R.sub.2 and R.sub.3 are H.
- 10. A process according to claim 1 wherein R is alkoxy and R.sub.1, R.sub.2 and R.sub.3 are H.
- 11. A process according to claim 1 wherein R is amide and R.sub.1, R.sub.2 and R.sub.3 are H.
- 12. A process according to claim 1 wherein R.sub.4 is H.
- 13. A process according to claim 1 wherein R.sub.4 is alkyl.
- 14. A process according to claim 1 wherein ##STR6## is derived from ethylene, propylene, isobutylene, methylvinyl ether, styrene or vinyl pyrrolidone.
- 15. A process according to claim 1 in which said optional amine is present.
- 16. The polymer product of the process of claim 1.
