Abstract
PURPOSE: To prepare a cinchona-alkaloid acrylonitrile copolymer having improved thermal stability, by reacting a cinchona-alkaloid with acrylonitrile in the presence of a radical polymerization initiator generating carbon radicals.
CONSTITUTION: One mole of a cinchona-alkaloid expressed by formulaI: (R is H or a protective group for hydroxyl group; R1 is H or alkoxy group) is reacted with one or more moles of acrylonitrile in the presence of a radical polymerization initiator which generates carbon radiclas, e.g. azobisiobutyronitrile, azobis-1- cyclobutanenitrile, etc. in an aprotic polar solvent under an inert atmosphere at 50W 100°C for 10W50hr to give a cinchona-alkaloid-acrylonitrile copolymer of formula II: (x and n are integers expressing the number of repeating units).
