Abstract

A new group of polymer flow controllers for powder resin lacquer is provided. The polymer flow controllers contain groups ##STR1## wherein n and m are numbers from 0 to 1000 with the sum of n+m=2-1000 and R.sub.1 and R.sub.2 are independently hydrogen, an optionally hydroxy substituted hydrocarbon group containing 1 to 36 carbon atoms aryl and aralkyl optionally substituted in the aromatic nucleus, or R.sub.3 --(--O--C.sub.2 H.sub.4 --)--.sub.p O--CH.sub.2 -- wherein R.sub.3 is an alkyl or alkenyl group containing 1 to 18 carbon atoms and p is a number of 1 to 10.
