Co-Curing of EPDM and Diene Rubbers by Grafting Accelerators Onto EPDM

Rubber Chemistry and Technology, 1974
Abstract The object of this work was to find ways to co-cure blends of EPDM and diene rubbers for improved properties. We found that by grafting accelerators onto EPDM we obtain excellent cure compatibility between EPDM and natural rubber.

Crystallinity in EPDM terpolymers

British Polymer Journal, 1979
AbstractThe crystallinity of a series of ‘medium‐high’ green strength EPDM terpolymers has been examined by X‐ray diffraction and thermal analysis. It has been found that the crystallinity of such materials can vary from 0.20% as measured by thermal analysis, and depends on the E:P ratio in the polymer.

The Compatibilization of EPDM/SBR Blends by EPDM-Graft-Styrene Copolymer

Polymer-Plastics Technology and Engineering, 2005
Ethylene propylene diene rubber (EPDM) and styrene butadiene rubber (SBR) blends were compatibilized by a graft copolymer EPDM-graft-styrene. This compatibilizer was prepared by gamma radiation induced grafting of EPDM with styrene monomer. The compatibilized blends were evaluated by scanning electron microscope and dielectric properties.

ADVANCEMENTS IN EPDM SPONGE COMPOUND PROCESSING USING EPDM BIMODAL POLYMERS

Rubber Chemistry and Technology, 2011
Abstract Ethylene-propylene-diene (EPDM) elastomers are the primary polymer choice for automotive weatherseal applications due to their outstanding weathering and heat resistance properties. Automotive sealing systems are complex in design; in particular, door seals are one of the most complex components of the sealing system, generally ...

Polypivalolactone grafts on EPDM

Journal of Polymer Science: Polymer Chemistry Edition, 1978
AbstractRandom copolymers of ethylene, propylene, and 1,4‐hexadiene (EPDM) were carboxylated by reaction with thioglycolic acid or with maleic anhydride. Treatment of these polymers in tetrahydrofuran solution with tetrabutylammonium hydroxide generated carboxylate anions, which initiated the graft polymerization of pivalolactone.

Spotlight on EPDM Elastomers

Polymer-Plastics Technology and Engineering, 1992
Abstract Etylene-propylene diene monomer (EPDM) rubbers have become widely recognized as an important class of elastomers in an enormous variety of consumer-type products. Typical examples where this material is used include seals around automotive doors, trunks, and windows; hosing materials used in automotive radiator applications, ply-roofing ...

Graft copolymer EPDM-g-PS as a compatibilizer in SAN/EPDM blends

2002
The efficiency of graft copolymer EPDM-g-PS on miscibility in SAN/EPDM blends has been studied. SAN/EPDM blends have poor physical and mechanical properties caused by their low miscibility. All studied samples were prepared by casting films from chloroform solution.
