USE OF CONDENSATION PRODUCTS OF FATTY ACIDS, ALCOHOLS, PHENOLS, ALKYL PHENOLS AND AMINES WITH ETHYLENE OXIDE AND/OR PROPYLENE OXIDE AS AN ESSENTIAL OR SOLE COMPONENT OF AN ADDITIVE

摘要

The invention concerns the use of condensation products of fatty acids, alcohols, phenols, alkyl phenols and amines with ethylene oxide and/or propylene oxide, either one or a mixture of several types of these condensation products, as a main (essential) or sole component of an additive in compacting wet powders of admixtures to polymers, or an additive for admixtures to polymers in powder form. Using additives according to the present invention low dusting and in polymers well dispersing powders or granulates/pellets are obtained, dispersibility of which is better or comparable to not adjusted form of a given admixture. Additives according to the present invention are added before compaction of admixtures to polymers in an amount of 0.01 to 15 weight parts, preferably of 0.1 to 2 weight parts with respect to 100 weight parts of a given admixture to polymers. They are added in the given range also in the production of final powder forms of admixtures to polymers. Additives according to the present invention may be applied to all types of water-insoluble admixtures to polymers. They are especially suitable for rubber chemicals like, for example, vulcanization agents, vulcanization accelerators, vulcanization activators, pre-vulcanization inhibitors, antidegradants, anti-reversion agents, surfactants, fillers and the like.
