    摘要: The instant invention relates to a method for making processable ionic polymer compositions which are characterized as being processable at high temperatures, for example, 200.degree. C, while retaining adequate physical properties at both room temperatures and elevated temperatures which are below the processing temperature, for example, up to 100.degree. C and more. In this method, an ionic polymer comprising an elastomeric or plastic backbone and pendant acid groups is combined with a first neutralizing agent having two components. One component of said neutralizing agent is a metal or ammonium type moiety which combines with the pendant acid groups as a metal or ammonium salt thereof; the other component of neutralizing agent takes up the hydrogen ion present in the pendant acid groups and is converted into a preferential plasticizer for said ionomer. The preferential plasticizer acts to disrupt the ionic association of the metal or ammonium salt groups, thus allowing the ionic polymer to act as a noncrosslinked material. When the composition is in this state, it can be compounded with oils, fillers, etc. An ionic composition in this state is also characterized as having poor physical properties, for example, tensile strength, and excellent processing characteristics, e.g., low viscosity at elevated temperatures. This neutralized composition is then contacted with a second neutralizing agent which acts to substantially convert said preferential plasticizer to a higher melting species, for example, a salt. The composition, after the second neutralizing step, is then characterized as having the desired properties, for example, excellent physical properties at room temperature and up to 100.degree. C and more than adequate processability at temperatures of from 200.degree. C and above. Preferably, the ionic polymer is an ionic elastomer having from 0.2 to 25 mole % pendant acid groups, for example, carboxylic, phosphonic and sulfonic acid groups. Preferably, the pendant acid groups are sulfonic acid groups.The first neutralizing agent is preferably selected from the group consisting of metal salts of fatty acids wherein said metal is selected from Groups IA, IIA, IIB, IIA, Al and Pb of the Periodic Table of the Elements or ammonium salts of fatty acids said ammonium moiety has the general formula R.sub.4 N wherein R is selected from the group consisting of hydrogen and lower alkyl, e.g., methyl and ethyl, more preferably hydrogen radicals.The second neutralizing agent is preferably selected from the group consisting of Group IA, IIA and IIB derivatives of lower organic acids, for example, from 1 to 4 carbon atoms and their hydroxides. Preferably, the first neutralizing agent is combined with said ionic polymer at from 0.5 equivalents/equivalent of acid to 5 equivalents/equivalent acid and more preferably from 1 equivalent/equivalent acid to 3 equivalents/equivalent acid and said second neutralizing agent is combined with said ionic polymer preferably at from 0.25 equivalent/equivalent acid to 3 equivalents/equivalent acid, and more preferably between 0.75 equivalent/equivalent acid and 3 equivalents/equivalent acid.

    摘要: The instant invention relates to unique and novel ionic polymer compositions which are characterized as being processable at high temperatures, for example, 200.degree. C., while retaining adequate physical properties at both room temperature and elevated temperatures which are below the processing temperature. The ionic polymer compositions include a metal neutralized sulfonated polymer which is plasticized with a preferential plasticizer, at a concentration level of about at least 7 parts by weight per 100 parts of the metal neutralized sulfonated polymer. The preferential plasticizer acts to disrupt the ionic association of the metal or ammonium salt groups of the neutralized sulfonated polymer, thus allowing the ionic polymer to act as a noncrosslinked material at the processing temperature. When the composition is in this state, it can be compounded with oils, fillers, etc. The plasticized metal neutralized sulfonated polymer has excellent physical properties at room temperature and up to 100.degree. C. and more than adequate processability at temperatures of from 200.degree. C. and above thereby providing a proper balance of rheological and physical properties. Preferably, the ionic polymer is an ionic elastomer having from 0.2 to 25 mole % pendant acid groups, for example, carboxylic, phosphonic and sulfonic acid groups. Preferably, the pendant acid groups are sulfonic acid groups.
