Associative monomers and polymers |
| 摘要 |
Novel mono- and multi-functional non-ionic urethane monomers are prepared from surfactants comprising poly(ethylene oxide)(butylene oxide) copolymers, preferably C1-C4 alkoxy-terminated, monohydric, ethylene oxide/butylene oxide block polymers and monoethylenically unsaturated aliphatic isocyanates. When polymerized with, e.g. acrylic acid or alkyl acrylates, these monomers provide copolymers exhibiting greatly enhanced thickening efficiency.
