Cable filling and flooding compositions are disclosed in which a carrier component such as process oil, mineral oil, synthetic oil, liquid polybutene or petrolatum is modified by the inclusion of high density polyethylene byproduct wax, a homo or partially crystalline copolymer of ethylene and, optionally, amorphous polypropylene and block copolymer to provide finished compositions with the application temperature viscosities, slump and other characteristics desirable for cable fill and flood applications. |

DETAILED DESCRIPTION What is claimed is: 1.
A modified wax composition comprising: from about 45 to about 98 weight percent high density polyethylene wax ("HDPE wax"); from about 2 to about 50 weight percent of an ethylene polymer selected from the group consisting of homopolymers and partially crystalline copolymers of ethylene and an alphaolefin selected from the group consisting of 1-butene, 1-hexene, 1-octene and 1-decene; and from about 0 to about 50 weight percent of a substantially amorphous homopolymer or copolymer of polypropylene, said HDPE wax having a density of from about 0.
93 to about 0.
96 g/cm.
sup.
3, a number average molecular weight ("Mn") of from 500 to 3,000 and a melt viscosity at 300.
degree.
F.
of from 5 centipoise to 500 centipoise, and said ethylene polymer having a density of from 0.
88 to 0.
93 g/cm.
sup.
3 and a number average molecular weight ("Mn") of from 10,000 to 100,000, said modified wax composition being noncross-linked and being suitable for use in the preparation of cable fill and flood compounds.
2.
The composition according to claim 1 comprising additionally from about 0.
02 to about 5 weight percent of an antioxidant.
3.
A composition comprising an admixture of: a first component comprising, from about 45 to about 98 weight percent HDPE wax, from about 2 to about 50 weight percent of an ethylene polymer selected from the group consisting of homopolymers and partially crystalline copolymers of ethylene and an alphaolefin selected from the group consisting of 1-butene, 1-hexene, 1-octene and 1-decene, and from about 0 to about 50 weight percent of a substantially amorphous homopolymer or copolymer of polypropylene; and a second component selected from the group consisting of mineral oil, liquid polybutene, polymerized alphaolefin, process oil and petrolatum, said HDPE wax having a density of from about 0.
93 to about 0.
96 g/cm.
sup.
3, a number average molecular weight ("Mn") of from 500 to 3,000 and a melt viscosity at 300.
degree.
F.
of from 5 centipoise to 500 centipoise, and said ethylene polymer having a density of from 0
