摘要： The present invention provides a polymerizable unsaturated group-containing cyclodextrin derivative, which can be efficiently prepared with a higher yield and a higher purity, and which can be mass-produced.
The polymerizable unsaturated group-containing cyclodextrin derivative is represented by the following general formula (1).




(In the formula, R1 represents any one of



(A) the following general formula (2)






—R3—NH—R4   (2)





(R3 is an alkylene group having 3 to 20 carbon atoms, may be linear or branched, and may have a substituent.
R4 represents a (meth)acryloyl group or a vinyl group-containing alkyl group having 3 to 50 carbon atoms.)


(B) the following general formula (3)






—R5—NHCONH—R6   (3)





(R5 is an alkylene group having 3 to 20 carbon atoms, may be linear or branched, and may have a substituent.
R6 represents a (meth)acryloyloxyalkyl group having 4 to 50 carbon atoms or a vinyl group-containing alkyl group having 3 to 50 carbon atoms), or


(C) the following general formula (4)






—R5—OCONH—R6   (4)





(R5 and R6 are the same as those described above.)






R2 represents a hydrogen atom, an acyl group having 2 to 50 carbon atoms, or an alkyl group having 1 to 30 carbon atoms.
Rc represents a group represented by the following general formula (5).




(In the formula, R7's are the same as or different from each other, and each represent a hydrogen atom, an acyl group having 2 to 50 carbon atoms, an alkyl group having 1 to 30 carbon atoms, or —CONHR8 (R8 is an alkyl group having 1 to 20 carbon atoms), and 20% or more of R7's is any one of an acyl group having 2 to 50 carbon atoms, an alkyl group having 1 to 30 carbon atoms, or —CONHR8. x is an integer of 5 to 7))
