1、The tacticity of polymers is mainly influenced by the coordination ability of organotin monomers and polymers.

2、DSCDSC studies on high-tacticity polyacrylonitrile for high module and high strength carbon fiber

3、The invention discloses a tacticity regulator used for propylene polymerization and an application of the regulator.

4、The production technologies of PVA with ultrahigh relative molecular weight mass and high stereo-tacticity were introduced.

5、The conclusion is that the low tacticity polypropylene has a wide market foreground and the altered original unit has good economic benefit.
