A linear aminoplast-ether copolymer of formula (I), where the divalent R01 con- tains a divalent alkyleneoxy containing moi- ety, Amp is the skeletal residue of an amino- plast, R is hydrogen, alkyl containing 1 to about 4 carbon atoms, and acyl containing 1 to about 4 carbon atoms, p is a positive number that is equal to the free valence of Amp minus 2, RO is bonded to alkylene units of Amp, and a is a number greater than I. The method for making the copolymer is descried. |
