摘要:Novel processes towards the synthesis of the antiviral valomaciclovir stearate in which an esterified guanine acetal is reduced to the corresponding alcohol, reacted with an activated amino acid and N-deprotected. The esterified guanine acetal is prepared from a 9-guanine derivative bearing an acyclic hydroxymethylbutylacetal. The processes are amendable to one-pot reactions.

摘要:The invention relates to the field of polymer chemistry, more in particular to the synthesis of novel biobased linear polymers and their applications, among others as rheology modifiers or thickeners in waterborne formulations. Provided is a method for providing a linear carbohydrate-based polyester, comprising (i) reacting a bicyclic acetalized galactaric acid derivative (Galx) with a diol in the presence of a suitable catalyst to obtain a Galx -based polyester; and (ii) subjecting said Galx -based polyester to a hydrolytic deacetalisation reaction to convert at least part of the diacetal moieties to chhydroxide moieties.

标题:Use of tristyrylphenol alkoxylate sulfosuccinates in emulsion polymerization and coatings

摘要:Disclosed are the use of novel surfactants for the synthesis of emulsion polymer latexes, particularly those used in paints, coatings, and pressure sensitive adhesives. The surfactant compositions for emulsion polymer latexes comprise sterically bulky surfactants whose composition comprises at least one alkoxylated polyaryl substituted aromatic sulfosuccinate compound. The novel surfactants provide for the production of stable, small particle size distribution emulsion polymer latexes. The resulting latexes, when formulated into latex paint, impart improvements in water resistance as measured by film opacity, blister resistance and improved leveling characteristics, and when formulated into pressure sensitive adhesives, provide improved water resistance characteristics as measured by film opacity.
