COLLECTOR INTENDED TO BE USED IN DEINKING OF WASTE PAPER ACCORDING TO THE FLOTATION PROCESS

摘要

A collector that is intended to be used at deinking of waste paper according to the flotation process. The collector includes a polyester obtained through reaction between polyalkylene glycol, di and/or tricarboxylic acid and/or anhydrides thereof as well as a saturated fatty acid with 12-18 carbon atoms. The polyester shows a molecular weight between 3000-10000.
