Title: HYPERBRANCHED POLYOXYALKYLENE COMPOUND AND METHOD FOR PRODUCING SAME
Abstract:
Disclosed is a hyperbranched polyoxyalkylene compound, an aqueous solution of which shows low viscosity. Also disclosed is a method for producing the hyperbranched polyoxyalkylene compound. Specifically disclosed is a hyperbranched polyoxyalkylene compound which is represented by formula (1). (In the formula, R1s may be the same or different and each represents a hydrocarbon group having 1-24 carbon atoms; OA1 and OA2s may be the same or different and each represents an oxyalkylene group having 2-4 carbon atoms; n and m's may be the same or different and each represents an average mole number of added oxyalkylene groups, namely n represents a number of 0-1000 and m's may be the same or different and each represents a number of 10-1000; X represents a functional group which is capable of forming a chemical bond by reacting with an amino group, a mercapto group, an aldehyde group, a carboxyl group, a triple bond or an azide group; and L1 and L2 may be the same or different and each represents a single bond, an alkylene group, or an alkylene group having at least one bond selected from among an ester bond, a urethane bond, an amide bond, an ether bond, a carbonate bond and an amino bond.)
