PROCESS FOR REMOVAL OF VOLATILE COMPOUNDS FROM TACKIFIERS

Process for the removal of volatile compounds from a tackifier comprising a resin with repeating units of formula I wherein R1 is a linear or branched alkylen group with 1 to 10 carbon atoms and R2 is a linear or branched, saturated or unsaturated aliphatic hydrocarbon group with up to 20 carbon ato...

Zusammenfassung:	Process for the removal of volatile compounds from a tackifier comprising a resin with repeating units of formula I wherein R1 is a linear or branched alkylen group with 1 to 10 carbon atoms and R2 is a linear or branched, saturated or unsaturated aliphatic hydrocarbon group with up to 20 carbon atoms, and optionally a plasticizer, wherein the tackifier is passed through at least one evaporator as film and the volatile compounds are removed from the film. L'invention concerne un procédé d'élimination de composés volatils d'un agent poisseux comprenant une résine ayant des motifs de répétition de formule I dans laquelle R1 est un groupe alkylène linéaire ou ramifié ayant de 1 à 10 atomes de carbone et R2 est un groupe hydrocarboné aliphatique linéaire ou ramifié, saturé ou insaturé ayant jusqu'à 20 atomes de carbone, et éventuellement un plastifiant, l'agent poisseux ayant traversé au moins un évaporateur sous forme de film et les composés volatils étant éliminés du film.
