Abstract

A substituted melamine additive being a mixture of the formula ##STR1## wherein the six R substituents represent the following: (a) 0 to 3 are hydrogen; PA1 (b) 1 to 5 are R'--OCH.sub.2 --, wherein R' is a member selected from the group consisting of hydrogen and alkyl having from 1 to 4 carbon atoms; PA1 (c) 1 to 4 are substituents selected from the group consisting of R.sup.2 OCH.sub.2 --, R.sup.2 COOCH.sub.2 --, R.sup.2 CONHCH.sub.2 --, mixtures thereof, wherein R.sup.2 is a hydrocarbon group having 8 to 28 carbon atoms, and PA1 (d) 0 to 2 are substituents selected from the group consisting of Z--CH.sub.2 --O--CH.sub.2 -- and Z--CH.sub.2 --, wherein Z is a melamine group of the formula ##STR2## The substituted melamine additives are useful as additives in molding compositions based on thermosetting condensation resins to improve the moldability of the composition.
