“…Ionomers of ethylene-propylene-diene copolymer (EPDM) or butyl rubber can be prepared by sulfonation in solution with acetyl sulfate and behave as thermoplastic elastomers in the presence of an ionic plasticizer. [1][2][3][4][5] Xie and Xu 6 pointed out that it is not necessary to use zinc stearate during the processing of alkylamine neutralized ionomers of sulfonated butyl rubber. However, Fitzgerald and Weiss 7 pointed out that rubber with a higher unsaturation degree cannot be sulfonated in solution at concentrations over 3% so as to avoid gelation.…”

“…SBS was first epoxidized by performic acid in the presence of a phase-transfer catalyst; this was followed by a ring-opening reaction with an aqueous solution of alkali salt of bisulfate. The optimum conditions for the ring-opening reaction of the epoxidized SBS with an aqueous solution of KHSO 4 were studied. During the ring-opening reaction, both phase-transfer catalyst and ring-opening catalyst were necessary to enhance the conversion of epoxy groups to ionic groups.…”

A method for the synthesis of novel sulfated ionomer of styrene-butadiene-styrene triblock copolymer (SBS) was developed. SBS was first epoxidized by performic acid in the presence of a phase-transfer catalyst; this was followed by a ring-opening reaction with an aqueous solution of alkali salt of bisulfate. The optimum conditions for the ring-opening reaction of the epoxidized SBS with an aqueous solution of KHSO 4 were studied. During the ring-opening reaction, both phase-transfer catalyst and ring-opening catalyst were necessary to enhance the conversion of epoxy groups to ionic groups. The products were characterized with Fourier transform infrared spectrophotometry and transmission electron microscopy (TEM). After the potassium ions of the ionomer were substituted with lead ions, the lead sulfated ionomer exhibited dark spots under TEM. Some properties of the sulfated ionomer were studied. With increasing ionic groups or ionic potential of the cations, the water absorbency and emulsifying volume of the ionomer and the intrinsic viscosity of the ionomer solution increased, whereas the oil absorbency decreased. The sulfated ionomer possessed excellent emulsifying properties compared with the sulfonated SBS ionomer. The sodium sulfated ionomers in the presence of 10% zinc stearate showed better mechanical properties than the original SBS. When the ionomer was blended with crystalline polypropylene, a synergistic effect occurred with respect to the tensile strength. The ionomer behaved as a compatibilizer for blending equal amounts of SBS and oil-resistant chlorohydrin rubber. In the presence of 3% ionomer, the blend exhibited much better mechanical properties and solvent resistance than the blend without the ionomer. SEM photographs indicated improved compatibility between the two components of the blend in the presence of the ionomer.

A review of issues relevant to the definition, measurement, and classification of stimuli, situations, and environments. Problems such as the lack of adequate definitions of concepts, error and bias in measurement procedures, confusion between measurement of a concept and measurement of its behavioral effects, and the lack of agreement among alternative measures are emphasized. It is suggested that concepts be defined in terms of objective characteristics while allowing for the study of the transactional relationship between organism and environment. The work of the ethologists in defining stimuli while studying their relationship to different organismic states and situational contexts is emphasized in this regard. Following Brunswik, it is also suggested that wherever possible there be a representative sampling of variables in natural settings.
