碩士 === 國立中興大學 === 化學工程學系 === 89 === Abstract
The nuclephilic substitution reaction of poly(oxyalkylene)amine and cyanuric chloride (cc) gives a series of derivatives in a selective manner by controlling the reaction temperature. The structures of these derivatives are constituted of the hydrophobic poly(oxypropylene)-segments and hydrophilic poly(oxyethylene)-segments which could interact with water by hydrogen bonding. As a resalt, the cyanuric chloride derivatives was proved to be a polymeric surfactant.
First, this study was investigated with respect to the selectivity of cyanuric chloride with Jeffamine® M-2070. By varying the molar ratios of M-2070 and temperature, the suitable reaction conditions of the three avtive sites in cyanuric chloride was found (0oC、25oC、130oC). The structures were determined by GPC.
Furthermore, a family of block copolymers with different molecular weights and stuctures were prepared by using the selective reactions of cyanuric chloride and polyetheramines. Their fundamental surfactancy has been discussed. These polymeric surfactants lowered the surface tension of water and interfacial tension of water/toluene (or water/n-hexane) to 29~35 dyne/cm and 2.1 dyne/cm, respectively. Some adducts exhibited cloud points similar to the nonionic surfactants. The higher cloud point temperatures were observed for the higher HLB values.
