Abstract:
A hydrophilic polymer derivative having a benzylidene acetal linker whose hydrolysis rate at the pH of a weakly acidic environment in the living body can be accurately controlled. A hydrophilic polymer derivative having a benzylidene acetal linker, which is represented by the following formula (1): wherein R 1  is a hydrogen atom or a hydrocarbon group; R 2 , R 3 , R 4 , R 5 , and R 6  are each independently a hydrogen atom or a substituent and at least one of R 3 , R 4 , and R 5  is an electron-withdrawing substituent or at least one of R 2  and R 6  represents a substituent; X 1  is a chemically reactive functional group; P is a hydrophilic polymer; w is an integer of 1 to 8; and Z 1  and Z 2  are an independently selected divalent spacer.

Claim (Index 3):
The hydrophilic polymer derivative according to  claim 1 , wherein w is 1 and P is represented by the formula (5): wherein X 2  is a chemically reactive functional group different from X 1 ;\n Z 3  is a divalent spacer; \n n is an integer of 3 to 1000; and \n v is 0 or 2.
