A process produces a mono vinyl ether, R&#x2014;O&#x2014;CH&#x2550;CH. R represents an organic group with at least three carbon atoms. The process involves reacting a mono hydroxy compound. R&#x2014;OH, with acetylene in presence of a catalyst to get a product mixture containing the mono vinyl ether, unconverted mono hydroxy compound, and the catalyst. To the product mixture, an ester is added that contains at least one ester group, X&#x2014;OC&#x2014;. X is a hydrocarbon group containing less carbon atoms than R. The remaining mono hydroxy compound R&#x2014;OH is reacted with the ester in the presence of the catalyst to get a transesterification product containing at least one ester group, R&#x2014;OC&#x2014;, and an alcohol, X&#x2014;OH. The mono vinyl ether is isolated from the product mixture obtained after the ester addition, optionally followed by purification of the mono vinyl ether by distillation.

Process to produce a mono vinyl ether

A tackifier comprising a resin with repeating units of formula (I) wherein Ris a linear or branched alkylen group with 1 to 10 carbon atoms and Ris a linear or branched, saturated or unsaturated aliphatic hydrocarbon group with up to 20 carbon atoms and a non-aromatic compound which consists to at least 50% by weight of one or more linear or branched, saturated or unsaturated aliphatic hydrocarbon groups with at least 4 carbon atoms.
