Abstract:
1. A method for making a reactive terpolymer comprising the steps of: a) obtaining a predetermined amount of a functionalized maleic anhydride (FMA) with gelation prevention characteristics by heating a predetermined amount of a maleic anhydride with a predetermined amount of a free radical generation catalyst comprising benzoyl peroxide in a toluene solvent at 120° C., for a predetermined amount of time, wherein said predetermined amount of said free radical generation catalyst consists of at least 50% by weight of said predetermined amount of said maleic anhydride; b) cooling said predetermined amount of FMA to room temperature level; c) mixing said predetermined amount of FMA with a predetermined amount of vinylic monomers wherein said vinylic monomers comprises a styrene to obtain a predetermined amount of styrene-functionalized maleic anhydride (SFMA); d) mixing said predetermined amount of SFMA with a predetermined amount of a transfer agent, wherein said transfer agent comprises a 3-mercaptopropionic acid, to obtain a first solution; e) adding said first solution to a second solution wherein said second solution is selected from a group consisting of a predetermined amount of natural rubber, synthetic rubbers, crumb rubber, thermoplastic elastomers (TPE) and a combination thereof, along with a predetermined amount of toluene to obtain a third solution; f) heating said third solution to obtain said terpolymer, wherein said terpolymer further comprises formation of nano sized polymers of SFMA copolymer that is dispersed throughout said terpolymer.
