Abstract: An insect pest-repelling film or sheet is disclosed, having a reflective spectrum in a ultraviolet region of a wavelength of less than 0.4 .mu.m, particularly a reflective spectrum peak at a wavelength of less than 0.4 .mu.m, a reflective spectrum having not less than 1.4 of a ratio (R.sub.A /R.sub.B) of the ultraviolet reflectance (R.sub.A) and a visible light reflectance of a wavelength of 0.5 .mu.m (R.sub.B) and a visible light transmission of not less than 40%. The film is useful as a cover of houses and tunnels or mulching of ground for crop culture or as a repellent for various insect pests in agriculture, forestry, and gardening.

Abstract: A vibration-damping material with excellent workability consisting of two metal plates and a vibration-damping layer of a thermoplastic resin interposed between the two metal plates, in which the vibration-damping layer of a thermoplastic resin consists of a film as a middle layer and a polyolefin type resin (B) provided on both sides of the film as an upper and lower layer, the film as the middle layer being composed of (1) at least one resin (A) selected from the group consisting of polyolefin type resins and ionomer resins each having a modulus of elasticity in shear at 20.degree. C. of 3.times.10.sup.9 to 1.times.10.sup.7 dyne/cm.sup.2, a percentage of elongation at 20.degree. C. of 50% or above and a peak temperature of dissipation factor (tan .delta.) of -120.degree. C. to 80.degree. C. or (2) a resin mixture of the resin (A) and a synthetic rubber having a percentage of elongation at 20.degree. C. of 100% or above and a peak temperature of dissipation factor (tan .delta.) of -120.degree. to 50.degree.

Abstract: An infrared radiation absorbing film suitable for agricultural purposes comprising a first layer of olefin resin containing an amorphous hydrated aluminosilicate gel and optionally, additional layers of an olefin resin encompassing said first layer.

Abstract: An ethylene-.alpha.-olefin copolymer composition comprising two ethylene-.alpha.-olefin copolymers which are different in density, intrinsic viscosity and the number of short chain branching per 1000 carbon atoms. Extrusion processed materials, injection molded materials and films obtained from said composition are excellent in strength.

Abstract: An adhesive composition comprising (1) a polyolefin having therein at least one repeating unit containing a carbonyl group and (2) at least one of calcium chloride, magnesium chloride or a mixture thereof.
