  • Patent number: 7829636
    Abstract: The embodiments herein relate to a method of synthesizing new improved reactive terpolymer, S-MMA-X (styrene/modified maleic anhydride/X) wherein X is any type of polymers. The method involves synthesizing styrene-modified maleic anhydride complex (SMMA) with the ability to react with all kinds of polymers to produce new reactive terpolymer with formation of nano particles inside them. The nanoparticle formations improve the physio-chemical, thermal and mechanical properties of the newly formed reactive terpolymer when compared to natural rubber, their derivatives, EPDM or other known polymer etc. Depending on the property of the end product polymers produced by the invention, the end use can be varied. In one embodiment, the polymer X is natural rubber (NR) and the end product terpolymer is used as bitumen modifier. In another embodiment, the polymer X is ethylene-propylene diene monomer (EPDM) and the end product terpolymer behaves like a smart particle and absorbs oil and water contaminants.

  • Publication number: 20080058470
    Abstract: The aim of this invention is to synthesize new polymers which can be used for bitumen modification, oil absorption and other purposes. It was done by synthesizing styrene-modified maleic anhydride complex (SMMA) which has ability to react with all types of polymers and forms nano particles inside them. Indeed it is the formation of nano particles inside the polymers which cause such a great changes in physical, chemical, thermal and mechanical properties. None of the known derivatives of natural rubber or EPDM for examples shows the properties which have seen in this invention. The nature of the polymer determines the end use of the novel products. If the polymer is natural rubber (NR), the resulting novel polymer can be used for bitumen modification. They are compatible with bitumen, melt, react and disperse in bitumen readily without needing to special equipments for blending. The resulting composition is homogenous and demonstrates improved settling and rheological properties at high and low temperatures.
