Disclosed is a process for the production of a thermoplastic polymer containing carbon and sulphur in an atomic ratio of C:S of at least 4 and at most 36 using thiol-ene addition polymerization, preferably with feedstocks obtained from renewable resources such as fatty acids from vegetable origin. The product is preferably aliphatic, meaning that at most 70% of the protons are present as aromatic hydrogen atoms and, if oxygen atoms are present in ester functions, the atomic ratio of the oxygen atoms present in ester functions relative to the number of sulphur atoms in the polymer is less than 1.0. The polymer may be used to produce a shaped article.

A thiolactone derivative of 10-undecenoicacid was used as a renewable AB′ monomer for the one-pot synthesis of diversely substituted polyamide structures, containing amide moieties both in the polymer backbones and in their side chains. Nucleophilic aminolysis of the thiolactone entity liberates a thiol, which further reacts in a stepwise thiol–ene photopolymerization reaction. Using different primary
