COPOLYMER COATING |
| 摘要 |
A copolymer for a protective coating is formed from a mixture of .alpha. , .beta. -ethylenically unsaturated monomer, .alpha. , .beta. ethylenically unsaturated carboxylic acid monomer, and amphiphilic monomer. The protective coating has an average molecular weight of 7000 to 25000 to provide the desired properties of rapid drying, substantial film strength, and easy removal with an alkaline aqueous solution.
