摘要： Flooding compounds for telecommunications cables. Such flooding compounds contain a polymeric filler and a branched olefinic fluid. The branched olefinic fluid has an average of at least 1.5 methine carbons per oligomer molecule and at least 40 methine carbons per one thousand total carbons. Additionally, the average number of carbons per molecule in the branched olefinic fluid is from 25 to 200.

In an embodiment an adhesive composition is provided and includes (A) a propylene-based interpolymer having a density from 0.850 g/cc to 0.900 g/cc; (B) an ethylene-based polymer composition having a melt viscosity at 140° C. from 10 mPa*s to 1,000 mPa*s; and (C) a tackifier. The composition has a molecular weight distribution ratio from 1.00 to 1.40, wherein the molecular weight distribution ratio is the molecular weight distribution of the propylene-based interpolymer of component (A) compared to the molecular weight distribution of the ethylene-based polymer composition of component (B). The composition has a density ratio from 0.93 to 1.30, wherein the density ratio is the density of the propylene-based interpolymer of component (A) compared to the density of the ethylene-based polymer composition of component (B).
