    摘要： Embodiments of the present disclosure include flexible impregnated articles, composites produced by curing such flexible impregnated article, and processes for forming flexible impregnated articles. The flexible impregnated articles, composites, and processes can be used as alternatives to articles, composites, and processes in a cured-in-place pipe rehabilitation process that include epoxy resins, thus eliminating toxicity issues associated with the use of epoxy resins. The instantly-disclosed flexible impregnated articles, composites, and processes can be particularly useful for the CIPP process in potable water pipe and pressure pipe applications.

    摘要： The invention is related to compositions suitable for the fabrication of pipes, and other articles, with excellent performance properties. The invention provides a composition, comprising a blend, wherein said blend comprises a high molecular weight ethylene-based interpolymer and a low molecular weight ethylene-based interpolymer, and the high molecular weight ethylene-based interpolymer is a heterogeneously branched linear or a homogeneously branched linear ethylene-based interpolymer, and has a density from 0.922 g/cc to 0.929 g/cc, and a high load melt index (I21) from 0.2 g/10 min to 1.0 g/10 min, and the low molecular weight ethylene-based interpolymer is heterogeneously branched linear or a homogeneously branched linear ethylene-based interpolymer, and has a density from 0.940 g/cc to 0.955 g/cc, and a melt index (I2) from 6 g/10 min to 50 g/10 min. The blend has a single peak in an ATREF profile eluting above 30° C., and has a coefficient of viscosity average molecular weight (CMv) less than −0.0032 in the log (calculated Mv) versus elution temperature, said CMv calculated in the range of elution temperatures from 70° C. to 90° C. The Mv is the viscosity average molecular weight.
