Usage

General Description

Poly(ethylene glycol) divinyl ether is a chemical compound that consists of multiple ethylene glycol units connected by ether linkages, with each end functionalized with vinyl groups. It is a versatile polymer that can be used in a wide range of applications, including as a crosslinking agent in the production of hydrogels, as a precursor for the synthesis of various copolymers, and as a component in the formulation of adhesives, coatings, and other materials. Its high reactivity and ability to form stable crosslinked networks make it valuable for use in industries such as medical, pharmaceutical, and industrial manufacturing. Additionally, its hydrophilic nature and biocompatibility make it suitable for use in biomedical applications, such as drug delivery systems and tissue engineering scaffolds.

PROCESS FOR PREPARING DIVINYL ETHERS

Process for preparing divinyl ethers by reacting compounds having two hydroxyl groups (hereinafter referred to as diols) with acetylene, wherein the hydroxyl groups are incompletely reacted with acetylene and the resulting product mixture therefore comprises the monovinyl ether in addition to the divinyl ether andthe monovinyl ether is separated off from the product mixture by extractive distillation in the presence of an extractant.

Purification of alkenyl compounds

A process for purifying alkenyl compounds having a divalent or trivalent heteroatom in the à-position relative to the double bond by distillation comprises carrying out at least two distillations in which the purified alkenyl compounds are obtained from the gas phase by condensation, where the time between the first distillation after the synthesis of the alkenyl compounds and at least one further distillation is at least one day and the purified alkenyl compounds have an APHA color number of 30.
