Abstract

The polyurethane prepolymers, which were previously synthesized from 2,4-toluene disocyanate(2,4-TDI) and polypropylene glycol(PPG), were chain extended by ethylene diamine or hydroxyl terminated polydimethylsiloxane(HTPMS) having hydroxy group at both ends of the chain, giving polyurethaneurea(PU) and polyurethane containing HTPMS segment(SiPU), respectively. In thermal gravimetric analysis, PU was almost completely degraded at $500^{circ}$ but SiPU showed about 11% residue at the same temperature. Suspension of SiPU and pigment showed more good compatibility than that of PU and pigment. The crocking fastness, migration fastness and solvent wicking were enhanced to 4.5 grades, 4 grades and 4 grades, respectively.
