Patent number: 6596815Abstract: An ionomer/high density polyethylene (HDPE) blend with improved flow (e.g., lower viscosity) can be achieved without significantly degrading physical properties such as impact resistance and tensile strength by the addition of low molecular weight ethylene/acrylic acid copolymer (e.g., so-called acid wax polymer derived from copolymerizing at least 5 weight percent and preferably greater than 9 weight percent acrylic acid and/or methacrylic acid with ethylene and having a melt index, ASTM D1238, preferably greater than 900 dg/min and preferably greater than 5,000 dg/min). The blend may further have for every one hundred parts by weight of ionomer/high density polyethylene blend from one to twenty parts by weight polyethylene modified with from 0.2 to 5.0 weight percent maleic anhydride comonomer as an impact resistance additive.Type: GrantFiled: January 25, 2002Date of Patent: July 22, 2003Assignee: E.

Patent number: 6593386Abstract: An expanded cellular ethylenic polymer product is provided from an irradiated, noncross-linked linear ethylenic polymer. Linear ethylenic polymers can be irradiated at ambient conditions sufficient to introduce branching in the polymer in the absence of detectable cross-linking as indicated by the absence of gels. The irradiated linear ethylenic polymer is compatible with highly branched low density polyethylene and, when mixed therewith, produces a resin having a single broad based melting temperature range as determined by direct scanning calorimetry, which indicates that the polymers in the mixture have similar crystallization behavior suitable for producing low density foams by extrusion foaming. The linear polymers can be obtained from recycled shrink wrap film. Low densities of from 0.7 to less than 4 pcf can be achieved. The foams typically have improved tear resistance as compared to previous products prepared from low density polyethylene, at comparable low densities.Type: GrantFiled: September 13, 1999Date of Patent: July 15, 2003Assignee: Sealed Air Corporation (U.S.)Inventors: Nelson E.

Patent number: 6590034Abstract: A peelable seal comprises a mixture of at least two immiscible polymers. The first polymer forms a continuous phase in the peelable seal, whereas the second polymer is dispersed in the continuous phase. For example, a peelable seal can also be made from a mixture of an ethylene polymer with a melt index in the range from about 0.1 to about 20 g/10 minutes and a propylene polymer with a melt flow rate in the range from about 0.01 to about 2 g/10 minutes. The two polymers define a shear viscosity differential: &Dgr;=|(&eegr;1−&eegr;2)/&eegr;1|, wherein &eegr;1 and &eegr;2 are the respective shear viscosity for the first and second polymers at a temperature of 230° C. and a shear rate of about 100 radian/second. Preferably, the shear viscosity differential is less than about 100%.Type: GrantFiled: December 18, 2001Date of Patent: July 8, 2003Assignee: Dow Global Technologies Inc.Inventors: Jeffrey A.

Patent number: 6579944Abstract: A thermoplastic vulcanizate (TPV) is produced by melt blending until the volume fraction of dispersed rubber particles is greater than 0.5 preferably from 0.55 to 0.95, the remaining being the dispersed continuous plastic phase in a manner so as to develop a morphology which generates optimum elastic recovery. The majority (by volume) of large rubber particles are adjacent a small particle which is separated from one or more large particles by a critically thin, less than 0.1 $G(m)m thick, ligament of deformable plastic. When the majority of large particles evidence this morphology, as seen in a transmission electron microscope (TEM) photomicrograph, the TPV exhibits unexpectedly higher elastic recovery than if the ligaments were thicker. The foregoing is simulated in a micromechanical model which confirms, and in retrospect, predicts the observed actual elastic recovery of the TPV.Type: GrantFiled: January 15, 2002Date of Patent: June 17, 2003Assignee: Advanced Elastomer Systems LPInventors: Sabet Abdou-Sabet, Kenneth Emery Kear, Mary C.
