| Research Abstract |
Performance enhancement of polybenzoxazines were attempted by various ways. High molecular weight benzoxazines were prepared by using various types of solvents, and the relation of chemical structure and properties of benzoxazines was made clear. Modification of the high molecular weight benzoxazines further improved the properties. Liquid crystalline benzoxazines were prepared by the combination of appropriate mesogen and flexible unit. Introduction of vinyl group or pyridyl group afforded much improved thermal properties for the cured polymer by the formation of further crosslinking or by the stronger hydrogen bonding. Copolymerization of the double bond with various vinyl monomers gave cured polymer having tough and much improved thermal properties.
