INTRODUCTION
Polybenzoxazine is a novel class of thermosetting polymer which has various outstanding properties such as high thermal stability, easy processability because of its low melt viscosity, low water absorption, near zero shrinkage after processing with excellent mechanical properties, and its ability to alloy with various types of resins. The monomers of this resin can be synthesized by a solventless method and produce no by-product during polymerization. Other advantage of this new resin is an ability to alloy with several kinds of resins. Alloying of benzoxazine resins with other resins was reported by many researchers. For example, the addition of ...
