Abstract
Modified scrap rubber particles, a method for forming the modified rubber particles and compositions including the modified rubber particles. The rubber particles are impregnated with at least one polymerizable monomer and polymerized to impregnate the rubber particles with a polymer. The impregnated polymer provides the modified rubber particles with improved properties which increase the potential uses for recycled scrap rubber. The modified rubber particles are useful in surface coatings, such as latex paint or powder coatings and can be used as a soil substitute.

A method of forming a composition including rubber particles, the method comprising:
- providing a quantity of the rubber particles;
- impregnating an interstitial molecular space with a hydrophobic polymerizable monomer;
- and
- reacting the hydrophobic polymerizable monomer to form a hydrophilic polymer impregnating the interstitial molecular space of the rubber particles.
A method of forming a composition including rubber particles, the method comprising:
- providing a quantity of the rubber particles;
- impregnating the rubber particles with a first polymerizable monomer comprising a hydrophobic monomer;
- impregnating the rubber particles with a second polymerizable monomer comprising a hydrophilic monomer;
- and
- polymerizing the first polymerizable monomer with the second polymerizable monomer to impregnate the rubber particles with a hydrophilic polymer to form modified rubber particles.
