TECHNOLOGY FOCUS - POLYMERS - Preparation (Claimed): Preparation of (I) comprises: preparing polyethylene glycol methacrylate monomers (PEGMA) and methacrylic acid monomers substituted with 12-22C alkenyl having 1-6 double bonds (ACMA); and copolymerizing the monomers by mixing PEGMA and ACMA monomers in organic solvent and adding an initiator to the mixture. Preferred Definitions:    L1 = -NHCO-, -COO-, -COS-, -O-, -S-, -S-S-, 2-10C aliphatic radical, preferably mono or poly unsaturated aliphatic hydrocarbon or aryl radical;    n, m = 17:1-1:1; and    A1 = cardanol, preferably 1-methoxy-3-((8E,11E)-pentadeca-8,11,14-trienyl)-benzene, 1-methoxy-3-((8E,11E)-pentadeca-8,11-dienyl)-benzenealkenyl, 1-methoxy-3-((E)-pentadec-8-enyl)-benzene, or 1-methoxy-3-pentadecyl-benzene, or unsaturated fatty acids, preferably 5-dodecenoic acid, 7-tetradecenonic acid, palmitoleic acid, vaccenic acid, paullinic acid, oleic acid, elaidic acid, eicosenoic acid, erucic acid, nervonic acid, linoleic acid, gamma -linolenic acid, dihomo- gamma -linolenic acid, arachidonic acid, alpha -linolenic acid, eicosapentaenic acid, and/or docosahexaenic acid.    EXAMPLE - 0.188 g Azobisisobutyronitrile, 4.85 g poly(ethyleneglycol)8.5 methyl ether methacrylate, 0.5 g 2-methyl-acrylic acid 2-hydroxy-3-(((8E,11E)-3-pentadeca-8,11,14-trienyl)-phenoxy)-propyl ester and 11 ml anisole were placed into a 50 ml Schlenk flask equipped with a condenser and the reaction mixture was deoxygenated by three freeze-pump-thaw cycles and then stirred for 15 hours in an oil bath thermostatted at 60 degrees C. The reaction mixture was chilled using liquid nitrogen and exposed to air in order to terminate further polymerization, and then monomers not participated in the reaction and by-products were removed by precipitating to obtain polymer 2-ethyl-2,4,4-trimethyl-pentanedioic acid 5-(2-hydroxy-3-(((8E,11E)-3-pentadeca-8,11,14-trienyl)-phenoxy)-propyl) ester 1-(2-methoxy-ethyl)ester of formula (II) (average molecular weight of 12500-20000).    p = 8.5.
