Abstract
New unsaturated alcohol-thioether, in which a double bond is located in the beta position to the S atom, in an aliphatic chain which can repeat. The compounds are generally of the formula ##STR1## In this formula, A is a branched or unbranched aliphatic chain which may be substituted or unsubstituted, and preferably contains from 2-6 carbon atoms; R.sup.1, R.sup.3 and R.sup.4 may be the same or different, and are aliphatic groups and/or hydrogen atoms; R.sup.2 is an aliphatic group, hydrogen, alkylene, or a bond and p gives the degree of polymerization of the beta-unsaturated aliphatic chain. These compounds may be prepared by the reaction of a mercapto-alcohol with a conjugated diene in the presence of a free radical catalyst.
