FUNCTIONALIZATION AT THE DOUBLE-BOND REGION OF JOJOBA OIL .8. CHEMICAL BINDING OF JOJOBA LIQUID WAX TO A POLYMER MATRIX VIA AN AMINE SPACER

摘要

Jojoba wax was chemically bonded to a polymer matrix via stable C-N covalent bonds. The polymer matrix was prepared by amination of several types of styrene-divinyl benzene or styrene-vinylbenzylchloride-divinylbenze copolymers with diamines or polyethylene imines (polyamines). The jojoba wax was attached to the aminated polystyrene matrix by reacting an allyl-brominated derivative of jojoba with the matrix to form a C-N bond between the matrix and the jojoba wax. The amount of bound jojoba wax added to the polymer was in the range of 20-70% (w/w), depending on the type of polymer matrix and reaction conditions. The double-bond regions in the jojoba wax bonded to the matrix were preserved, and they were subsequently functionalized by phosphonation and sulfur-chlorination reactions. [References: 35]
