摘要:
Multi-stage polymer particles comprising at least one hydrophobically-modified, ionically-soluble polymer stage polymerized from a) hydrophobic monomer, b) ethylenically-unsaturated, ionizable monomer, c) non-ionic, ethylenically-unsaturated monomer and optionally d) multi-functional compound are improved thickeners.
