POLYMERIC PIPES MADE FROM BLENDS OF POLYOLEFINS AND VINYL ALCOHOL POLYMERS |
| 摘要 |
A pipe that comprises a melt-mixed bend of vinyl alcohol polymer and incompatible polyolefin and a compatibilizing agent where the vinyl alcohol polymer exists as a discontinuous phase that is dispersed in a polyolefin matrix. The pipe has enhanced resistance to the permeation of hydrocarbons and hydrocarbon/alcohol mixtures relative to polyethylene.
