    摘要: Provided is a polymerizable composition including (meth)acrylate monomers having at least two sulfide (—S—) linkages in the monomer. The polymerizable compositions include a first (meth)acrylate monomer represented by the following Formula (I), where L1 is selected from a multivalent optionally substituted hydrocarbyl group optionally interrupted with at least one of —C(O)—, —S—, —O— and combinations thereof, and a divalent linking group represented by the following Formula (A). In Formula (A), Y is O or S. Also in Formula (I), L2 is independently for each n a divalent optionally substituted hydrocarbyl group optionally interrupted with at least one of —O— and —S—, R1 is independently selected for each n from hydrogen and methyl, and n is from 2 to 6. The polymerizable compositions also may include a polymerization moderator. Also provided are polymerizates including photochromic articles and optical elements prepared from such polymerizable compositions.

    摘要: A process For the production of a thermoplastic polymer including carbon and sulphur in an atomic ration 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.
