Synthesis and Characterization of a New Magnetic Polyurethane Material

Abstract:

Magnetic polyurethane was synthesized by a prepolymerization body method using poly(1,4-butylene adipate glycol), 4,4'-diphenylmethane diisocyanate, 1,4-butyl glycol, and a magnetic chain extender. The magnetic chain extender is synthesized by a method involving the use of dimethylolpropionic acid (DMPA) and ferrous powder in dimethyl formamide as solvent conditions. Fourier-transform infrared spectroscopy is used to characterize the magnetic chain extender, and the rheological properties of magnetic Polyurethane are measured by a torque rheometer.
