Photopolymerizable thioacrylate monomers
摘要:
A novel photocurable monomer having the formula: ##STR1## wherein: Ar is arylene;R.sup.1 is H, alkyl, alkoxy, amino, halogen, sulfide, sulfoxide, sulfonate, aryl or heterocyclic;R.sup.2 is H, alkyl, aryl or aralkyl; andR.sup.3 is H or methyl,is useful in preparing a polymer having a high refractive index. The polymer is useful in optical components, such as lenses.
