Abstract
The disclosure of this application is directed to a composition suitable for use in the fabrication of spiral wound hose comprising a mixture of a substantially linear ethylene polymer having a density of about 0.915 to about 0.935 and a melt index of about 0.1 to about 10.0, produced under low pressures, and an alkylene-alkyl acrylate copolymer containing at least about 19 percent by weight combined alkyl acrylate and having a melt index of about 0.5 to about 6.0.
Claims8
A composition comprising a subsequently linear ethylene polymer having a melt index of about 0.1 to about 10.0 and a density of about 0.915 to about 0.935 and in an amount of about 20 to about 90 percent by weight, an alkylene-alkyl acrylate copolymer having a combined alkyl acrylate content of at least about 19 percent by weight and having a melt index of about 0.5 to about 6.0.
A composition comprising a substantially linear ethylene polymer having a melt index of about 0.3 to about 2.0 and a density of about 0.919 to about 0.925 and in an amount of about 40 to about 70 percent by weight, an alkylene-alkyl acrylate copolymer containing about 19 percent by weight combined alkyl acrylate and having a melt index of about 1.0 to about 2.0.
