Claim Text:
1. A polymerizable oligomer comprising a polymerizable double bond and a hydrophilic group, wherein the monomers or compounds for the synthesis of the polymerizable oligomer are: one or more of a polymerizable double bond-containing organic ester monomer, a polymerizable double bond-containing organic acid monomer, and a polymerizable double bond-containing organic acyl chloride monomer; a compound containing a polymerizable double bond and a hydroxyl group; and a hydrophilic group-containing compound, wherein the polymerizable oligomer is prepared from an oligomer (a), the compound containing a polymerizable double bond and a hydroxyl group, and a the hydrophilic group-containing compound; wherein the oligomer (a) is polymerized from the polymerizable double bond-containing organic ester monomer, the polymerizable double bond-containing organic acid monomer and the polymerizable double bond-containing organic acyl chloride monomer, in which parts by weight of each monomer are the organic ester monomer: 6; the organic acid monomer: 1-3; and the organic acyl chloride monomer: 3-1.
