权利要求: We claim:.-1. An oil-soluble polymer of (A) polymerizable oilsolubilizing compounds having a single ethylenic linkage and containing a monovalent hydrocarbon group of from 4 to 30 aliphatic carbon atoms and (B) at least one eth-yienically unsaturated acyl amido alkyl ether of polyalkylene glycol selected from the group consisting of polyalkylene glycols having a molecular weight between about 220 and 30,000, and from 2 to 7 carbon atoms in each alkylene group and monoalkyl ethers thereof, said acyl group having from 3 to 20 carbon atoms and said amido alkyl group having from 2 to 7 carbon atoms, said (A) component constituting from about 40 to 96% by weight and said (B) component constituting a total of from about 4 to 60% by weight of the polymer composition, there being present at least one monomer of said (B) component and said polymer being substantially saturated and having a molecular weight of at least 50,000 as determined by standard light scattering methods and a solubility in oil of at least 0.5% by weight, said polyglycols having at least 5 alkylene oxide units each and being attached by a single amino group to said polymer.2. A polymer according to claim 1 in which the (A) component is alkyl methacrylate wherein the alkyl group contains from 8 to 30 carbon atoms and the (B) component is methacrylamido ethyl monoether of polyethylene glycol.3. A polymer according to claim 1 in which the (A) component is alkyl methacrylate wherein the alkyl group contains from 8 to 30 carbon atoms and the (B) component is methacrylamido propyl monoether of polyethylene glycol.4. A polymer according to claim 1 in which the (A) component is dodecyl methacrylate and the (B) component is methacrylamido ethyl monoether of polyethylene glycol.
