-30- ABSTRACT This invention is directed to alkyl-substi- tuted thiapolycyclic polyahls and to polymers prepared therefrom. The polyahl is represented by the structural formula: Image wherein A is a residue of an active hydrogen moiety, Image is a thiapolycyclic moiety having at least 6 carbons and a sulfur-containing bridging group and x is 0, 1 or 2; each R1 is independently an alkyl group containing 1 to 3 carbon atoms; each R2 is independently hydrogen or methyl provided that at least two R2 are hydrogen; y is a number corresponding to available valences for the polycyclic ring; and n is 0, 1, 2 or 3. -30-
