Beschreibung
Zusammenfassung:	The present invention relates to improved acid etch resistant polymers and coatings, and their method of preparation whereby polyurethane polyols, which because of long alkyl side chains that include a single ether group in the chain, when reacted with a melamine compound, such as, hexakismethoxymethylmelamine, form coatings that have excellent solubility in hydrophobic solvents and provide films with excellent acid etch resistance. The polymers, because of their excellent acid etch resistance and exterior durability can be used for automotive clear coats or single coats.
