ABSTRACT:
Synthetic resin compositions of improved resistance to deterioration by heat and light are provided containing a 2,2,6,6-tetramethyl piperidyl ether having the formula: ##STR1## The compounds of the invention can be prepared by the reaction of the 2,2,6,6-tetramethyl piperidyl alcohol R.sub.1 -OH with (poly) trimethylol alkane, (poly) pentaerthritol, or an alcohol containing an oxetane ring, to form the ether.
The etherification is carried out by the conventional method, for example, by the reaction of R.sub.1 -OH with the organic sulfonate of the above-mentioned alcohols, or by the reaction of R.sub.1 -OH with the halogenated above-mentioned alcohols in the presence of an alkali or acid acceptor.
The compounds where n is equal to 2 or more can be prepared by chain opening polymerization of the corresponding compound containing the oxetane ring.
