Quasi-living metal catalyst for ethylene (homo/co)polymerization

技术优势: • Increased wettability of olefinic substrate • Better adherence to polyolefin surface • High affinity for polymeric binders used in coatings and inks

技术应用: • Polyolefin materials • Primer coatings • Inks for dying, printing, painting This technology is available for licensing. Click here to request more information.

详细技术说明: Researchers at the University of California, Santa Barbara have developed a novel method for controlling the size of blocks in a block copolymer containing an olefinic block and a hydrophilic block. Block copolymers of this nature contain at least one segment capable of adhering to a polyolefin surface while also connected to polymeric segments that have high affinity with typical polar polymeric binders used in coatings and inks.

*Abstract: A method of using a novel quasi-living metal catalyst for homo-polymerization of olefins such as ethylene, α-olefins, and functionalized olefins and for co-polymerization of olefins with functionalities such as acetates.

*Applications: • Polyolefin materials

Background

Polyolefin materials, such as polyethylene and polypropylene, are used in a wide variety of applications and have a large commercial value. Polyolefin materials are the main ingredients in the manufacturing of blown film, various sports equipment and apparel, and some pharmaceutical and medical devices such as HEPA filters. Adhesion of other materials (paints and other coatings) to polyolefin is not completely sufficient by any current techniques. Corona treatment and primer coating are typically not effective and the use of chlorinated polyolefins presents several shortcomings associated with high cost, limited stability, and causation of environmental problems. There is a need for more commercially acceptable polymers that adhere to polyolefin materials in order to resolve issues concerning dying, printing, and painting processes as well as coating integrity and durability.
