摘要
Novel structural motifs in macromolecular chemistry are introduced by the use of the Asinger multicomponent reaction. The combination of ammonia, acetone, -chloroisobutyraldehyde, and either water or sodium hydrosulfide, leads to an oxazoline or thiazoline scaffold, respectively, which is subsequently modified with 10-undecenol and 10-undecenoyl chloride to obtain heterocycle-functionalized ,-dienes. These substrates are used as monomers in an acylic diene metathesis (ADMET) or thiol-ene step-growth polymerization. The thus-obtained polymers are studied in post-polymerization modifications, like hydrogenation and oxidation. Here, the thiazolidine- and oxazolidine-containing polymers show dramatically different chemical stability due to the heterocyclic moieties.
