  • Patent number: 9388306
    Abstract: In one aspect is a film comprising: (a) within the range of from 50 to 99 wt % linear low density polyethylene based on the weight of the core composition; and (b) within the range of from 1 to 50 wt % propylene-?-olefin copolymer based on the weight of the core composition, wherein the propylene-?-olefin copolymer possesses: (i) a melting temperature (Tm) of less than 105° C., and (ii) a heat of fusion (Hf) of less than 75 J/g; wherein the film is a cast or blown film. The films have excellent strength and elasticity and are ideal for such applications as stretch wrap.

  • Patent number: 5171793
    Abstract: A thermally polymerized hydrogenated hydrocarbon resin and a novel process for hydrogenating a hydrocarbon resin. The resin is a copolymer of a feed which is a mixture of styrene and indene and derivatives thereof and cyclodiene monomers and dimers and optionally acyclic dienes. The process for hydrogenation of hydrocarbon resins is a process in which the resins are hydrogenated in the presence of an olefinic diluent which increases the hydrogenation reaction temperature to improve hydrogenation efficiency. The resin is useful in block copolymer and ethylene-unsaturated ester copolymer adhesive systems.
