Abstract: Elastomeric polyolefin-based ionomers and methods for making same. The ionomers can include a copolymer comprising: C2-C60 ?-olefin monomer units; optional C2-C60 ?-olefin comonomer units different than the monomer units; optional diene units; and about 0.1 wt % to about 20 wt % metal alkenyl units, based on the weight of the copolymer, wherein the metal alkenyl units have the formula —R(A?)—, wherein R is an alkyl group containing 2 to 10 carbon atoms, and A? is an anionic group. The copolymer can further include one or more metal cations derived from the group consisting of alkali metals, alkaline earth metals, group 3-12 metals, group 13-16 metals, and combination(s) thereof. The ionomer has a glass transition temperature of ?60° C. to 5° C., and a weight average (Mw) of 50 to 5,000 kg/mol.

Abstract: A multipoint fuel delivery system for an internal combustion engine includes fuel metering device(s) such as fuel injector(s) associated for selectively controlled injection of the second fuel to corresponding combustion chamber(s) of the internal combustion engine. A fuel supply manifold associates with fuel injector(s) for directing the second fuel to each fuel injector. An intake port adaptor mechanism adapts the intake port of the associated combustion chamber to receive the selectively controlled injection of the fuel from an associated fuel injector. The intake port adaptor mechanism may also engage the intake port so as to permit selective flow of the first fuel or the second fuel to the intake port of the selected combustion chamber. A control mechanism selectively controls the flow of the second fuel through each injector(s).
