Ethylene may be copolymerized with numerous monomers but only a few such copolymers have achieved commercial status. The more important comonomers are propylene, 1-butene, vinyl acetate, ethyl acrylate and carboxylic acids. Ethylene-propylene copolymers are particularly important and are discussed in Sections 2.7 and 2.8. [Pg.58]

When first introduced there were strong grounds for believing that the ethylene-propylene rubbers, particularly the EPDMs, would achieve the status of general purpose elastomers. The principal... [Pg.339]
