Claims
- 1. A polymer, which contains, as a structural unit, a monomer unit shown by the general formula [1a](wherein X is a cyclic hydrocarbon residue which may have a substituent, Z is a spacer or a direct bond, and R is a substituted alkyl or alkenyl group having one or two protected hydroxyl groups as substituent).
- 2. A polymer as claimed in claim 1, wherein the cyclic hydrocarbon residue which may have a substituent, shown by X in the general formula [1a] is a group shown by any one of the general formulae [2a] to [4a] (wherein R16 to R19 are each independently a hydrogen atom, an alkyl group, a cyano group, an alkyloxycarbonyl group, an aryl group, an aralkyl group or a carbamoyl group, and n, a and b are 0 or 1).
- 3. A polymer as claimed in claim 1 or claim 2, wherein the substituted alkyl or alkenyl group, shown by R in the general formula [1a] is a group shown by the general formula [5](wherein R1 and R2 are each independently a hydrogen atom, an alkyl group, a substituted alkyl group or an alicyclic hydrocarbon residue, and R1 and R2 may form together an aliphatic ring, and R3 is an alkyl group, an alkenyl group, a hydroxyalkyl group, an alkyloxycarbonyl group or an alkylsilyl group) or a group shown by the general formula [6](wherein R4 is an alkyl group and R1, R2 and R3 have the same meaning as above, and R3 and R4 may form together an aliphatic ring).
- 4. A polymer as claimed in claim 1, wherein the substituted alkyl or alkenyl group, shown by R is a group shown by the following general formula [7], [8] or [8′](wherein R1′ is a hydrogen atom, R2′ and R3′ are a lower alkyl group having 1 to 4 carbon atoms and R1′ and R2′ may form together a lower alkylene group having 3 to 4 carbon atoms and Y and Y′ are a group shown by the formula [9] or the general formula [10]—CH2—CH2— [9]in which R4′ and R5′ are a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms).
- 5. A polymer as claimed in claim 1 or 2 wherein the spacer is a group shown by the general formula [11]&Parenopenst;COO&Parenclosest;m(A1)p&Parenopenst;A2&Parenclosest;q(A3)r— [11](wherein A2 is a divalent hydrocarbon residue which may contain an oxygen atom, A1 and A3 are each independently a lower alkylene group, m, p, q and r are each independently 0 or 1, provided that q is 1 when m is 1, and at least one of m, p, q and r is 1).
- 6. A polymer as claimed in claim 5, wherein the spacer shown by the general formula [11] is group shown by the general formula [12]&Parenopenst;COO)m′—(CH2)p′— [12](wherein m′ and p′ are each independently 0 or 1, provided that at least one of m′ and p′ are 1).
- 7. A polymer as claimed in claim 2, wherein R16 to R19 are a hydrogen atom.
