Abstract

See full text

A microdomained aqueous emulsion polymer is provided. The polymer comprises a first domain having a Tg of from −80 to −10° C. and comprising from 80 to 100 wt % of acrylic monomer; and a non-crosslinked second domain having a Tg of from 50 to 120° C. and comprising, as polymerized unit and based on the weight of the second domain, from 50 to 100 wt % of styrenic monomer; wherein the content of the second domain ranges from greater than 6 wt % to 30 wt % of the total weight of the first domain and the second domain. The polymer is suitable for applications including adhesives and binders, especially for pressure sensitive adhesives.
