Hydrophobically modified alkylene oxide urethane polymer |
| 摘要 |
The present invention relates to a composition comprising a hydrophobically modified alkylene oxide urethane polymer with pendant or end-capping tertiary amine groups, the conjugate acids of which have a pKa in the range of about 4.5 to about 6.5. The composition of the present invention is useful as a rheology modifier for paint formulations formulated over a wide pH range and is more stable to heat aging than higher pKa amine-modified HEURs. |

1. A composition comprising a hydrophobically modified alkylene oxide urethane polymer with pendant or end-capping tertiary amine groups, the conjugate acids of which have a pKa in the range of about 4.5 to about 6.5, wherein the tertiary amine groups are mono- or dihydroxyalkylated dibenzylamine groups. |
