Process for the removal of volatile compounds from 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 N 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. 

Process for removal of volatile compounds from tackifiers

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. 

Tackifier for rubber compositions

The present invention relates to a process for preparing autocatalytic polyether alcohols by reacting H-functional starter substances containing at least one amino group which is catalytically active in the urethane reaction, in particular a tertiary amino group, and at least one group which is reactive toward alkylene oxides, in particular a primary and/or secondary amino group and/or hydroxyl group, with alkylene oxides, which comprises

Device for producing polyether alcohols

The invention relates to mixtures (1) comprising (a) polytetrahydrofuran and (b) stabilizers having a molecular weight of from 600 g/mol to 10000 g/mol and comprising at least two phenolic groups.

Mixtures containing polytetrahydrofuran and a stabiliser

Catalysts contain, as structural units, at least one tertiary amino group and at least one group which, after its decomposition, is capable of complexing or protonating the tertiary amino group.

Catalysts, in particular for the preparation of polyisocyanate polyadducts

The polyisocyanate polyaddition products comprise hydrophobic compounds plus at least one further compound selected from the group consisting of: (i) organic, cyclic compounds having a molecular weight of from 200 to 3000 g/mol, (ii) salts of metals of transition groups I, II and/or VIII, (iii) organic and/or inorganic acid anhydrides, (iv) cyclic sulfonic esters and/or sulfones, (v) lactones, lactams and/or cyclic esters and/or (vi) &agr;,&bgr;-unsaturated carboxylic acids, &agr;,&bgr;-unsaturated carboxylic acid derivatives, &agr;,&bgr;-unsaturated ketones and/or &agr;,&bgr;-unsaturated aldehydes.
