Sulfonate esters polymers Polymer

Brase and coworkers used a similar concept to prepare sulfonic esters via polymer-bound triazenes [67]. The methodology was subsequently expanded to phosphoric and phosphinic acids with good results [68]. For the alkylation of sodium sulfonates, this method has the advantage that sulfene formation is...

The addition of specialized small molecules to a polymer coating is the functional basis for most photoresists. Conventional positive-working photoresists function owing to the difference in solubility caused by the imagewise exposure of a small molecule naphthalene diazoquinone sulfonate ester (NDS). The presence of this small molecule dramatically inhibits the dissolution of the novolac binder while its photodecomposition accelerates the binder dissolution in aqueous base. 

Sodium sulfhydride (NaSH) is a much better reagent for the formation of thiols (mercaptans) from alkyl halides than H2S and is used much more often. It is easily prepared by bubbling H2S into an alkaline solution, but hydrosulfide on a supported polymer resin has also been used. " The reaction is most useful for primary halides. Secondary substrates give much lower yields, and the reaction fails completely for tertiary halides because elimination predominates. Sulfuric and sulfonic esters can be used instead of halides. Thioethers (RSR) are often side products. The conversion can also be accomplished under neutral conditions by treatment of a primary halide with F and a tin sulfide, such as PhsSnSSnPhs. An indirect method for the preparation of a thiol is the reaction of an alkyl halide with thiourea to give an isothiuronium salt (119), and subsequent treatment with alkali or a... 

Polymerization in a single-phase homogeneous solution in THF/water mixtures (2 1) has also been reported [235]. Such reactions allowed for the preparation of a poly (p-phenylene) with sulfonate ester and dodecyl side groups [Eq. (10)]. By comparison to the aforementioned biphasic polymerizations, the synthesis of polymers with higher degrees of polymerization was reported in the solution procedure.

Sulfo groups (as a free acid, salt, or ester) can be introduced into polymers by homo- or copolymerization of monomers containing sulfo groups, or by direct sulfonation of the polymer.
