Abstract
An aqueous dispersion including (A) at least one base polymer selected from the group consisting of an ethylene-based co-polymer and a propylene-based co-polymer; (B) at least one polymeric stabilizing agent; and at least one filler; wherein the polymeric stabilizing agent is different from the at least one base polymer and is compatible with the at least one base polymer and the at least one filler, and wherein the dispersion has filler in the range of greater than 0 to about 600 parts per hundred parts of a combined amount of the at least one base polymer and the polymeric stabilizing agent is disclosed.
Claims11
An article comprising:
- a substrate;
- and
- a film associated at least with one surface of the substrate;
- wherein said film is derived from an aqueous frothed dispersion comprising;
- at least one base polymer selected from the group consisting of an ethylene based thermoplastic polymer, a propylene based thermoplastic polymer, and combinations thereof wherein said film comprises;
- at least one polymeric stabilizing agent;
- at least one filler;
- at least one frothing agent;
- and
- water;
- wherein said film comprises a continuous base polymer phase, and a discrete stabilizing agent phase dispersed in said continuous polymer phase.
A method for forming an article comprising the steps of:
- selecting an aqueous frothed dispersion comprising;
- at least one base polymer selected from the group consisting of an ethylene based thermoplastic polymer, a propylene based thermoplastic polymer, and combinations thereof wherein said film comprises;
- at least one polymeric stabilizing agent;
- at least one filler;
- at least one frothing agent;
- and
- water;
- selecting a substrate;
- applying said aqueous frothed dispersion to at least one surface of said substrate;
- removing at least a portion of the water;
- thereby forming a film associated with said substrate;
- wherein said film comprises a continuous base polymer phase, and a discrete stabilizing agent phase dispersed in said continuous polymer phase.
