Ruptureable, dual reagent mono-capsules are disclosed that have a core composition, which includes a first reagent, encapsulated within a polymer wall, and a shell connected to an exterior surface of the polymer wall by a surfactant. The shell is made from a second reagent that is chemically bonded to the surfactant by a chemical electrostatic interaction. Upon rupture of the polymer wall of the mono-capsule, the first reagent and the second reagent chemically react with one another to form a reaction product.

Problem to be Solved

One of the objects of the resent invention is to provide a new polybenzoxazine compound that can afford a cured product having excellent toughness, heat resistance and flame retardance without using other components together.

Solution

A benzoxazine compound represented by formula (1):

##STR00001## wherein n is an average repeating number and represents a real number of 1 to 5; R.sub.1 to R.sub.8 each independently represent a hydrogen atom, a halogen atom, an alkyl group having a carbon number of 1 to 8 or an aryl group; when n is 2 or more and the number of each R.sub.3 to R.sub.7 is 2 or more, each R.sub.3 to R.sub.7 may be the same or different; and R.sub.9 represents a residue of a monoamine compound from which an amino group is removed.
