标题:Synthesis of amine functional co-and terpolymers

摘要:Amine functional polymers are prepared by polymerization of vinylamides with vinyl ester monomers. The resultant polymers are hydrolyzed under acid conditions and subsequently at least partially basified to the free-base amine. Byproduct salts are removed by precipitation or by extraction into an immiscible phase. The polymers made by this method are crosslinkable through reaction of the amine groups and are useful in high performance coatings, adhesives, binders and the like.

摘要:The invention concerns a method for producing pulverulent hardening accelerators by reactive spray drying, where an aqueous phase I comprising calcium ions, and an aqueous phase II comprising sulphate ions, the molar ratio of the calcium ions to the sulphate ions being from 1/5 to 5/1, are contacted at a spray nozzle, and the phases I and II contacted with one another at the spray nozzle are sprayed in a streaming environment of drying gas. Likewise concerned are the pulverulent hardening accelerators producible by the method of the invention, and their use for accelerating the hardening of bassanite and/or anhydrite with formation of gypsum.

摘要:The present invention relates to enhancement of anti-tubercular activity of active fraction isolated from Salicornia brachiata . The invention also discloses the non-toxic nature of the fraction and positively identifies Sucrose as its main constituent. Pure Sucrose is shown to have no anti-tubercular activity indicating thereby that activity of the fraction resides in one or more of the minor constituents. The minor constituents are shown to be relatively low molecular weight entities and a chromatographic technique is disclosed for separating them from the bulk sucrose to probe their activities and structures in detail, as also the possibility of their synthesis if the leads thrown up are novel.
