ABSTRACT:
An alkenyl-substituted bisnadimide represented by the following formula [1]: ##STR1## [wherein R.sup.1 and R.sup.2 individually represent a hydrogen atom or a methyl group, and E is an alkylene.multidot.phenylene group or an alkylene.multidot.phenylene.multidot.alkylene group represented by the following formula [2]: ##STR2## (wherein a is an integer of 0 or 1, and R.sup.3 and R.sup.3' individually represent a C.sub.1 -C.sub.4 alkylene group or a C.sub.5 -C.sub.8 cycloalkylene group)], a process for the preparation of the same and a process for curing the same are disclosed. Further, an adhesive material and a coating material containing the bisnadimide as a curing component are also disclosed. A cured material obtaind from the bisnadimide has excellent heat resistance, mechanical strength, toughness, adhesion property to many kinds of substrates, and so on. The adhesive material shows excellent heat resistance and the coating material shows excellent boiling water resistance.
