Abstract
Process for the preparation of new esters of piperidinols, and in particular new esters of p-hydroxyaryl substituted alkyl or 2,2-dimethylpiperidin-4-ol substituted p-hydroxyaralkyl, suitable as stabilizers for polymers and especially for propylene, of the general formula I **(See formula)** where A is - (see formula), and R1 and R2 are the same or different and each is a straight or branched chain alkyl group having 1 to 6 carbon atoms, or 1-methylcyclohexyl, or alpha, alpha-dimethylbenzyl, and R3 and R4 are the same or different and each is an alkyl group with 1 to 12 carbon atoms, or R3 and R4 together with the carbon atom to which they are attached form a saturated alicyclic radical with 5 to 8 carbon atoms, or the formula group **(See formula)** and n is 0 or 1, characterized by reacting a piperidinol of formula IV **(See formula)** with an acid halide of formula V **(See formula)** where R1, R2, A and n have the meaning already expressed above, and Y is halogen, preferably chlorine; the reaction of which takes place in the presence of a halogenic acid binding agent, such as triethylamine, or, optionally, an excess of the reacting amine.
