<p>A method of improving the caustic stress-crack resistance of polyester containers for caustic applications comprises mixing between about 0.1 weight percent and about 99.9 weight percent of a nylon, with about 0.1 weight percent and about 99.9 weight percent of a polyester, wherein said percentages are based upon the combined weight of the polyester and nylon, to form a blend, and forming a container from the blend. Polyester made according to this invention has improved resistance to alkaline processing fluids, such as line lubricants and/or hydraulic fluids. A method of storing an alkaline product comprises placing an alkaline composition in a container, wherein the container comprises a blend of between about 0.1 weight percent and about 99.9 weight percent of a nylon and between about 0.1 weight percent and about 99.9 weight percent of a polyester, wherein said percentages are based upon the combined weight of the polyester and nylon.</p> |
