Graft copolymers from peroxidized EPDM rubber

Abstract: SynopsisThe transition metal catalyzed peroxidation of the pendant allylic functionality in EPDM rubbers with tertiary butyl hydroperoxide results in elastomeric, high polymer peroxides. The peroxidized EPDM rubbers are useful as free radical initiators for the polymerization and grafting of vinyl monomers in the preparation of comb-type structures. The grafted EPDM rubbers are efficient impact modifiers for thermoplastic resins so long as the polymer grafted onto the EPDM is identical to or is thermodynamical… Show more

“…During such a direct reaction, EVA in the solution phase is rapidly hydrolyzed to EVAL. In the first step of the process, EVA microspheres are saponified mainly on the surface in an alkaline methanolic solution 14, 15. In the present study, the reaction time and methanol concentration were controlled, such that the thickness of the saponified surface layer was about 40–50% of the original microsphere radius.…”

“…The monofunctional character of the 1,2-dihydro-benzocyclobutene group on the polyethersulfone would appear to be supported by: ( 1 ) the ability to mold test specimens and ( 2 ) the ability to obtain viscous flow in a melt index apparatus where the melt flow after 10 min at 3OOOC was 28.7 dg and after 30 min at 300°C was 26.4 dg. Additionally, the melt flow index extrudate after the 10 min exposure at 300°C was completely soluble in 1,2,4-trichlorobenzene ( 100°C).…”
