ABSTRACT:
Compounds of the formula I ##STR1## in which a is 1, 2 or 3, m is an integer from 2 to 20, R.sup.1, R.sup.2 and R.sup.3 independently of one another are hydrogen or methyl and R.sup.4 is an m-valent radical of a polyol after removal of m hydroxyl groups, can be thermally reacted to give crosslinked polymers having outstanding physical properties.
The polymers are suitable especially as casting resins, matrix resins, adhesives, encapsulating resins, insulating materials for electronics and electrical engineering and in surface protection.
