Abstract:
The invention relates to a hybrid latex comprising polymeric particles having core-shell structure, wherein: (1) the comonomers of the core comprise: (a) monovinyl aromatic compounds, and (b) unsaturated carboxylic acid esters; (2) the comonomers of the shell comprise: (a) monovinyl aromatic compounds, and (b) conjugated dienes; wherein the glass transition temperature of the core is in the range of −50° C. to 50° C., and the glass transition temperature of the shell is in the range of −50° C. to 50° C. The invention also relates to the use of the hybrid latex in polymer waterproofing membrane and polymer modified mortars.
