Polyisoprene Grafted Nanoparticles

Description:

 

Reference #: 01058

The University of South Carolina is offering licensing opportunities for a method synthesizing polyisoprene grafted nanoparticles to prepare rubber on silica surfaces.

Invention Description:

The subject invention is a new method for polymerizing isoperene on silica nanoparticle surfaces that allows more dispersion of silica fillers in the rubber or polyolefin matrix.

Potential Applications:

Functionalization of rubber for improved mechanical properties

Advantages and Benefits:

1.  Enhances the mechanical properties of the resulting composite materials

2.  The surface anchored polyisoprene possesses a much higher molecular weight than reports in literature, which is tremendously important for industry applications.

Background:

Polyisoprene is recognized as an important class of rubber materials for the automotive industry. It can be prepared in a variety of traditional ways, but few reports explore the polymerization of isoprene in a controlled manner. Polyisoprene contains many double bonds in the polymer backbone, which allows further functionalization and chemical modifications
