Abstract

A suitable reaction system, and proper conditions were designed to produce desirable polyurethane base THICKENER with a calculated number average molecular weight. Initially an ETHOXYLATED URETHANE prepolymer was synthesized by reaction of a polyethylene glycol (M n=6000) and dicyclohexylmethane diisocyanate using the step growth polymerization technique. MODIFICATION was carried out by reaction of cetyl alcohol with the resulting prepolymer. The SYNTHESIS of ETHOXYLATED URETHANE was investigated by using FTIR. Also1 H NMR was used for showing substituted hydrophobe parts. It was found that, the measured number average molecular weight of synthesized hydrophobically modified ETHOXYLATED URETHANE (HEUR) was in agreement with the calculated M n. The thickening efficiency of the modified ETHOXYLATED URETHANE was compared with a similar unmodified urethane. It was concluded that, the efficiency of modified ETHOXYLATED URETHANE is very high in comparison with the unmodified one, although the SYNTHESIS conditions were similar for both modified and unmodified urethanes.
