Embodiments of the present invention include a branched aromatic ionomer, and a process of making it, by co-polymerizing a first monomer comprising an aromatic moiety and an unsaturated alkyl moiety and a second monomer represented by the general formula:[R-A]-Mwherein R is a hydrocarbon chain having from 2 to 40 carbons and at least one polymerizable unsaturation; A is an anionic group; M is a cationic group; Z is &#x2212;1 or &#x2212;2; X is +1, +2, +3, +4, or +5; and y is an integer having a value of from 1 to 4. The branched aromatic ionomer has a melt flow index ranging from 1.0 g/10 min. to 13 g/10 min. Optionally the melt flow index ranges from 1.3 g/10 min. to 1.9 g/10 min.

Low melt flow branched lonomers

A biaxially oriented film that comprises polypropylene and either polytrimethylene terephthalate or polymethylpentene as a cavitating agent in an amount from 5 wt % to 25 wt %. The film has a haze of from 90% to 100% and a gloss of from 10 to 150. The film may be used in food packaging applications and in industrial applications.

Modifiers for oriented polypropylene

Disclosed is a polystyrene based polymer/layered compound nanocomposite for injection blow molding or injection stretch blow molding of articles. The nanocomposite can reduce shrinkage and warpage to the preform during the reheating process compared to neat polystyrene. The incorporation of layered compounds can increase the processability of PS preforms, help improve heating efficiency, and improve bottle mechanical properties. The layered compound can be treated with chemicals or compounds having an affinity with the styrene monomer or polystyrene, thus producing a treated layered compound having an affinity with the styrene monomer or polystyrene. The monomer and the layered compound can be combined prior to polymerization. The polymer and layered compound can be combined by solution mixing in a solvent. The layered compound can also be incorporated into the mixture by compounding a polymer product with the layered compound, or the combination of any of the above three approaches.

Polystyrene nanocomposites for blow molding applications

Low melt flow branched ionomers

An opaque polymer film is prepared by admixing high crystalline polypropylene with a microvoid causing filler and extruding to form a sheet that is then biaxially stretched to form an opaque film. End uses for these films include soda bottles, candy wrappers and synthetic paper.

Opaque films for use in packaging

Polymer articles and processes of forming the same are described herein. The processes generally include providing an ethylene based polymer, blending the ethylene based polymer with a modifier to form modified polyethylene and forming the modified polyethylene into a polymer article, wherein the polymer article exhibits a haze that is at least about 10% less than a polymer article prepared with a similarly modified polyethylene.

Articles formed from nucleated polyethylene

A polymeric composition having a MFR of less than 2 g/10 min. which when formed into a film has an oxygen transmission rate of equal to or greater than 300 cc/100 in/24 h at 73&#xb0; F. and 0% relative humidity per ASTM D 3895 and a water vapor transmission rate of equal to or greater than 0.5 g/100 in/24 hrs at 100&#xb0; F. and 100% relative humidity per ASTM F 1249. A polymeric film having a 2% secant modulus in the machine direction of 300 MPa to 700 MPa; an oxygen transmission rate of greater than 300 cc/100 in/24 h at 100&#xb0; F., a water vapor transmission rate of greater than 0.5 g/100 in/24 hrs at 100&#xb0; F. and 100% relative humidity; an Elmendorf tear strength in the MD of from 50 g to 400 g; an Elmendorf tear strength in the transverse direction of from 150 g to 400 g, a dart drop strength of from 200 g to about 500 g, a haze of from 0% to 85% and, gloss at 45&#xb0; of from 5% to 70%.

Breathable films

It has been discovered that the properties of sheet or film materials of broad molecular weight distribution ethylene/propylene rubber impact-modified heterophasic copolymer (ICP) can be improved by blending the ICP with a second polyolefin. The second polyolefin may be a syndiotactic polypropylene (sPP), a random copolymer (RCP) of propylene and comonomer (e.g. ethylene and/or butene) made using a Ziegler-Natta or metallocene catalyst, medium density polyethylene (MDPE), linear low density polyethylene (LLDPE), or low crystalline copolymer of propylene/&#x3b1;-olefin. Improvements include, but are not necessarily limited to, reduced motor amps, lower secant modulus, increased dart drop strength, increased gloss, reduced haze, increased elongation to yield, elimination of stress whitening, improved puncture resistance, and decreased seal initiation temperature. This sheet of film materials may be co-extruded with other resins or laminated with other materials after extrusion.
