| 560147000 | Sulfur in acid moiety | 15 |
| 20090287015 | SULFUR MODIFIED SILANES FOR THE ELABORATION OF HIGH REFRACTIVE INDEX MATERIALS - A composition having a polythiol reactant and an alkenyl silane reactant which are combined to form a polysulfide polysilane. In the process, the reactants are combined in a thiol-ene addition process driven by UV radiation. The polysulfide polysilane is then hydrolyzed and may be combined with other hydrolyzed compounds. For coatings, the polysulfide polysilane is hydrolyzed and may optionally be combined with nanoparticles. For bulk materials, the polysulfide polysilane is hydrolyzed, concentrated and heated to form a high refractive index material which can be used to form lenses. | 11-19-2009 |

| 20110245530 | PROCESS FOR PRODUCING PENTAERYTHRITOL MERCAPTOCARBOXYLIC ESTERS AND POLYMERIZABLE COMPOSITIONS CONTAINING THE ESTERS - A process for producing pentaerythritol mercaptocarboxylic ester by reacting pentaerythritol with a mercaptocarboxylic acid having a content of thioester formed by condensation of two molecules of the acid of 5% or below (in terms of area percentage) as determined by the high-performance liquid chromatography in the case of the total area of the mercaptocarboxylic acid and thioester formed by intermolecular condensation of the acid is taken as 100%. | 10-06-2011 |
| 20110245531 | PROCESS FOR PRODUCING PENTAERYTHRITOL MERCAPTOCARBOXYLIC ACID ESTER, PENTAERYTHRITOL MERCAPTOCARBOXYLIC ACID ESTER OBTAINED BY THE SAME, AND USE THEREOF - Pentaerythritol which contains none of the alkali metals and the alkaline earth metals or which contains at least one of these in a total amount of 1.0 weight % or smaller is reacted with a mercaptocarboxylic acid to produce a pentaerythritol mercaptocarboxylic acid ester. | 10-06-2011 |
| 20130217912 | PROCESS FOR PREPARING MERCAPTOALKYL CARBOXYLATES - In the acid-catalyzed esterification of mercaptoalkyl alcohols by means of carboxylic acids to form mercaptoalkly carboxylates, formation of undesirable, usually sparingly soluble by-products usually occurs. The process of the invention in the absence of acid catalysts avoids the formation of such by-products. Particularly when the esterification of the invention is carried out as reactive distillation using reactive column and residence vessel, good degrees of conversion can also be obtained without acid catalyst and at the same time the formation of the by-products can be largely avoided. | 08-22-2013 |
