Abstract
Group 4 metallocene polymers offer a wide variety of unique properties. Some of these are reviewed in this paper, including the ability to form fibers and to absorb laser radiation, thereby protecting materials containing them in small amounts; the possibility of becoming conductive materials through simple doping; increasing the productivity of damaged, old and mold-infested seeds through incorporation of plant growth hormones; and acting as anticancer drugs that inhibit a variety of human cancers including breast and pancreatic cancers.
Highlights
Metal-containing polymers offer properties and opportunities not available to other polymers because of the presence of the metal site
Since we found that metallocene-containing polymers offered a number of useful properties including spontaneously forming fibers [5], use as control release agent for plant growth hormones, PGHs [6,7,8,9,10,11], and moderate laser emissions when present in ppm
We have described the synthesis of a number of metallocene polymers that show an unusual ability to interact with laser radiation [12]
Summary
Metal-containing polymers offer properties and opportunities not available to other polymers because of the presence of the metal site. Group 4 metals represent the chemical family with the closest properties, making them difficult to separate. Even so, they are among the most important elements and their metallocenes show wide application in a number of diverse areas. The metallocene dichlorides are widely employed as steroregulating agents in the production of many important polymers including polypropylene and polystyrene and a variety of linear polyethylene materials [1,2]. Our focus is on their potential as incorporated units in polymers
