The BOPP film includes a polypropylene, an absence of a nucleating agent, and an additive blended with the polypropylene forming a polypropylene/additive blend, wherein the additive is potassium stearate.

Use of agents to reduce crystallinity in polypropylene for BOPP applications

A masterbatch may include a syndiotactic polypropylene and one or more additives. The one or more additives may be present in the masterbatch in an amount of at least 13 weight percent based on a total weight of the masterbatch. The masterbatch may be formed by mixing the one or more additives with the syndiotactic polypropylene. The masterbatch may be mixed with a resin to form a resin mixture.

Masterbatch formulation and formation

Polymer articles and processes of forming polymer articles are described herein. The processes generally include providing a propylene based polymer formed from a metallocene catalyst and melt processing the propylene based polymer to form a polymer article.

Polypropylene for reduced plate out in polymer article production processes

A process for producing high impact polystyrene including feeding at least one vinyl aromatic monomer, an elastomer, and a free radical initiator to a first linear flow reactor to form a reaction mixture. Polymerizing the reaction mixture in the first linear flow reactor to a point below the point at which phase inversion occurs to produce a first polymerization mixture and feeding the first polymerization mixture from the first linear flow reactor to a second linear flow reactor. Polymerizing the reaction mixture in the second linear flow reactor to at least a phase inversion point of the mixture to produce a second polymerization mixture and feeding the second polymerization mixture from the second linear flow reactor to at least a third linear flow reactor for post-inversion polymerization of the second polymerization mixture. The product stream can have an ESCR value of at least 10% toughness retained with less than 10 wt % rubber content.

Methods of making high impact polystyrene

A high impact polystyrene (HIPS) is made from styrene monomer and 3 to 20 wt % of an elastomeric component phase including polybutadiene rubber and styrene butadiene copolymer. The HIPS has a 60 degree gloss of 90 or more, a Gardner drop of at least 10 in-lb, and an Izod impact strength of 1.8 ft-lb/in or more. The HIPS can have salami morphology with rubber particle size between 1 and 1.3 microns.

High impact polystyrene with high gloss and high impact strength

A polymer blend and a method of making the same are provided. The polymer blend includes an ethylene-propylene (C-C) random copolymer and a modifier selected from the group consisting of a metallocene-catalyzed polyethylene-based copolymer, a metallocene-catalyzed polyethylene-based terpolymer, and a syndiotactic polypropylene homopolymer. The polymer blend may also include an organic peroxide for visbreaking the polymer blend. An end use article is made from the foregoing polymer blend. The end use article may be, for example, a film, an injection molded article, a compression molded article, a thermoformed article, and a fiber. The end use article is desirably a film having an Elmendorf tear strength of at least about 300 g/ply in the machine and transverse directions.

Properties of polyolefin blends and their manufactured articles

Articles of manufacture and a method of making the articles are provided. The articles of manufacture comprise CpFlu metallocene catalyzed polypropylene homopolymers and C&#x2013;Crandom copolymers having narrow molecular weight distributions and low xylene solubles (or extractables) contents. Because of a number of desirable properties, the polypropylene homopolymers and C&#x2013;Crandom copolymers may be used to prepare a wide variety of useful articles, including but not limited to cast films, such as packaging; fibers suitable for use in fabrics and carpet applications, and injection and blow molded items such as bottles.

End use articles derived from polypropylene homopolymers and random copolymers

A polymer blend and a method of making the same are provided.

The polymer blend may also include an organic peroxide for visbreaking the polymer blend. An end use article is made from the foregoing polymer blend. The end use article may be, for example, a film, an injection molded article, a compression molded article, a thermoformed article, and a fiber.

Syndiotactic polypropylene blends having a unique set of mechanical properties may be prepared by blending syndiotactic polypropylene with an ultra low density polyethylene and, optionally, an isotactic polypropylene random copolymer. The syndiotactic polypropylene blends of the present invention have been found to have improved impact strength, reduced haze, increased light transmittance, and reduced flexural modulus. It has been determined that the addition of about 10 to about 50 wt % of an ultra low density polyethylene plastomer to a syndiotactic polypropylene can greatly enhance mechanical toughness, particularly at low temperatures, while maintaining good optical clarity. These results are made possible by using a sPP material with good optical clarity and dispersing the ULDPE plastomer uniformly throughout the sPP matrix to act as a sort of impact modifier. Moreover, the addition of about 10 to about 50 wt % of an iPP random copolymer to the sPP matrix phase provides comparable or improved mechanical properties while also resulting in a significant reduction in injection molding cycle times. The syndiotactic polypropylene blends according to the present invention may be further processed according to accepted practices to make cast films, blown films, co-extruded films, laminated sheets, injection molded parts, blow molded containers, and other articles using basic plastic fabrication techniques as known in the art.
