Abstract:
A thermoplastic composition comprising a mixture of:a. a polyethylene oxide polymer having a weight average molecular weight that is between about 100,000 to about 20,000,000, wherein the polyethylene oxide polymer is present in the thermoplastic composition in a weight amount that is between about 5 weight percent to about 60 weight percent;b. a polyolefin polymer, wherein the polyolefin polymer is present in the thermoplastic composition in a weight amount that is between about 5 weight percent to about 40 weight percent;c. a polyester polymer having a weight average molecular weight that is between about 10,000 to about 2,000,000, wherein the polyester polymer is present in the thermoplastic composition in a weight amount that is between about 5 weight percent to about 70 weight percent, wherein all weight percents are based on the total weight amount of the polyethylene oxide polymer, the polyester polymer and the polyolefin polymer present in the thermoplastic composition; andd. a compatibilizer that exhibits a hydrophilic-lipophilic balance ratio that is between about 10 to about 40, wherein the compatibilizer is present in the thermoplastic composition in a weight amount that is greater than about 0 weight percent to about 25 weight percent;wherein the thermoplastic composition exhibits an Apparent Viscosity value at a temperature of about 200.degree. C. and a shear rate of about 1000 seconds.sup.- 1 that is between about 5 Pascal seconds to about 200 Pascal seconds.
