Claims
- 1. An amphiphilic polymer, consisting of the monomer unit structure: ##STR14## wherein R is at least one of H and C.sub.1-6 alkyl, k=1-4, n=2-50, x=2-500, p and q are, independently, 0-22, and the sum of p and q is 4-44; and compounds in which the ester group in said polymer is replaced by an amide, urea, urethane, ether or carbonate group.
- 2. An amphiphilic polymer, consisting of a monomer unit structure selected from the group consisting of: ##STR15## wherein R is at least of H and C.sub.1-6 alkyl, k=1-4, m=4-30, n=2-50, x=2-500, p and q are, independently, 0-22, and the sum of p and q is 4-44, r and s are, independently, 0-22, and the sum of r and s is in the range of 2-44, and Ar is a divalent aromatic radical.
- 3. The amphiphilic polymer of claim 1, wherein R=H.
- 4. The amphiphilic polymer of claim 2, wherein m=10-20.
- 5. The amphiphilic polymer of claim 1, wherein n=12-16.
- 6. The amphiphilic polymer of claim 1, wherein x is 3-20.
- 7. The amphiphilic polymer of claim 1, wherein said polymer has cationic, anionic or switterionic end groups.
- 8. The amphiphilic polymer of claim 7, wherein said end groups are selected from the group consisting of sulfonic acid, trialkylammonium phosphate, OPO.sub.3 R', --OC(O)CH.sub.2 PR'.sub.3.sup.+, --OC(O)CH.sub.2 SR'.sub.2.sup.+, and --OPO.sub.3 CH.sub.2 CH.sub.2 N(CH.sub.3).sub.3.sup.+ end groups, where R' is an alkyl group.
