摘要:
Disclosed are multi-staged acrylic based core-shell polymers comprising a linear core polymer and at least one subsequently polymerized shell polymers is crosslinked. The core-shell polymers surprisingly provide desirable rheological, clarity, and aesthetic properties in aqueous surfactant containing compositions, particularly at low pH.
