Claims
- 1. A surface active material comprising an alternating copolymer having the formula
- wherein X and Y respectively consist of a hydrophobic group and an ionic or non-ionic hydrophilic group,
- wherein said hydrophobic group is selected from the group consisting of aliphatic, cycloaliphatic, aliphatic heterocyclic and C.sub.9 -C.sub.18 amine groups; and wherein said hydrophilic group is selected from the group consisting of polyethylene oxide, copolymers of ethylene oxide-propylene oxide, C.sub.2 -C.sub.10 aliphatic and aromatic sulfonate, and carboxylic acid groups, wherein said copolymer has a molecular weight in the range of from about 1,000 to about 500,000.
- 2. The material of claim 1 wherein Y is a copolymer of ethylene oxide-propylene oxide.
- 3. The material of claim 1 wherein Y is a polyethylene oxide group.
- 4. The material of claim 1 wherein Y is a C.sub.12 primary amino group.
- 5. An electrically active material comprising an alternating copolymer having the formula ##STR12## wherein X and Y oppositely consist of an electron accepting group and an electron donating group, wherein said copolymer has a molecular weight in the range of form about 1,000 to about 500,000 and wherein said electron donating group is selected from the group consisting of N,N-dimethyl phenylene diamine, alkoxy anilines, substituted aromatic amines and dimethoxy benzoic acid.
- 6. The material of claim 5 wherein said electron accepting group is 3,5-dinitrobenzoic acid.
- 7. The material of claim 5 wherein said electron accepting group is 3,5 dinitro aniline.
- 8. A method for producing a material comprising an alternating copolymer having the formula ##STR13## wherein X and Y oppositely consist of an electron accepting and an electron donating group; or a hydrophobic and an ionic or non-ionic hydrophilic group and wherein said copolymer has a molecular weight in the range of from about 1,000 to about 500,000, which method comprises reacting 4-acetoxystyrene with maleic anhydride in the presence of a free radical initiator to form poly(4-acetoxystyrene alt maleic anhydride), then reacting this product with a primary amine to form a poly(4-hydroxystyrene/N-alkyl or aryl maleimide), and then 4-substituting said hydroxystyrene such that said N substituent and said 4-hydroxystyrene substituents oppositely consist of an electron accepting and an electron donating group or oppositely a hydrophobic and an ionic or non-ionic hydrophilic group.
- 9. The method of claim 8 wherein X is a polyethylene oxide group.
- 10. The method of claim 8 wherein X is a copolymer of ethylene oxide-propylene oxide.
- 11. The method of claim 8 wherein Y is a C.sub.12 primary amino group.
- 12. The method of claim 8 wherein said electron donating group is N,N-dimethyl phenylene diamine.
- 13. The method of claim 8 wherein said electron accepting group is 3,5-dinitrobenzoic acid.
- 14. The method of claim 8 wherein said electron accepting group is 3,5 dinitro aniline.
- 15. A surface active material comprising an alternating copolymer having the formula ##STR14## wherein Y and X respectively consist of a hydrophobic group and an ionic or non-ionic hydrophilic group, wherein said hydrophobic group is selected from the group consisting of aliphatic, cycloaliphatic, aliphatic heterocyclic and C.sub.9 -C.sub.18 amine groups; and wherein said hydrophilic group is selected from the group consisting of polyethylene oxide, copolymers of ethylene oxidepropylene oxide, C.sub.2 -C.sub.10 aliphatic and aromatic sulfonate, and carboxylic acid groups, wherein said copolymer has a molecular weight in the range of from about 1,000 to about 500,000.
- 16. The material of claim 15 wherein X is a copolymer of ethylene oxide-propylene oxide.
- 17. The material of claim 15 wherein X is a polyethylene oxide group.
- 18. The material of claim 15 wherein Y is a C.sub.12 primary amino group.
