<p>A water-based pressure sensitive adhesive formulation is provided with one or more high molecular weight linear aliphatic polymers. The resulting composition can be used to form stable filaments or delivered from the coating die of a premetered coater in the form of a stable sheet at a flow rate substantially less than the minimum delivery flow rate achievable using the formulation without polymer. Low levels of polymer can provide dramatic improvement in the viscosity of such compositions, without detrimental effect on the adhesive and other desirable qualities of the composition.</p> |
