ABSTRACT:
This invention relates to alk-1-enyl ether-polyester block prepolymers which are curable by cationically initiated radiation and which are defined by the formula ##STR1## wherein m has a value of from 1 to 25;
A is C.sub.2 to C.sub.12 alkylene, C.sub.6 to C.sub.14 aryl, both groups optionally substituted with lower alkyl, halo lower alkyl, alkyleneoxy, halogen or aryl;
R.sub.1 is alkylene containing from 1 to 6 carbon atoms;
R.sub.2 is a saturated or unsaturated divalent radical containing from 1 to 14 carbon atoms and is selected from the group of alkylene, alkenylene and arylene, each group optionally substituted with oxygen, halogen, lower alkyl and/or hydroxy;
R.sub.3 is hydrogen or C.sub.1 to C.sub.6 alkyl;
R.sub.4 is C.sub.1 to C.sub.6 alkylene, C.sub.6 to C.sub.14 arylene, lower alkyl substituted phenylene or xylylene and
R.sub.5 and R.sub.6 are independently hydrogen or C.sub.1 to C.sub.4 alkyl. The invention also relates to the method of preparing and curing the above prepolymer and to the use of the cured prepolymer as a hard, flexible protective coating possessing high density and superior resistance to abrasion and chemical attack.
