The present disclosure describes a composition including a sulfopolymer, and one or more agrochemicals. The composition exhibits increased rainfastness as compared to the same composition without the sulfopolymer. The present disclosure also describes methods of making and using such emulsion formulations in agriculture.

Polyethylene glycol (PEG)-b-poly(β-amino ester) (PBAE) co-polymers (PEG-PBAE) and blends of PEG-PBAEs and PBAEs and their use for delivering drugs, genes, and other pharmaceutical or therapeutic agents safely and effectively to different sites in the body and to different cells, such as cancer cells, are disclosed.

The invention relates to an oxidizing, ionic and short oil alkyd resin. The invention further relates to various compositions comprising the oxidizing, ionic and short oil alkyd resin, cured compositions derived upon curing of said compositions, objects comprising the various cured or uncured compositions as well as various uses of the oxidizing, ionic and short oil alkyd resin, and of the various compositions of the invention as well as of the various objects of the invention.

This invention relates to a process for preparing succinic acid and succinate ester from a succinic acid salt in fermentation broth. In the first stage of this invention, renewable carbon resources are utilized to produce succinic acid through biological fermentation. The succinic acid salt in the fermentation process is subjected to double displacement reaction with a strong acid leading to release of succinic acid. Succinic acid is recovered by fractional crystallization integrated with simulated moving bed chromatography to produce succinic acid and succinate ester.
