    摘要: A process for laminating a polar substrate with a film cast from a sulfonated block copolymer having at least one end block A and at least one interior block B wherein each A block contains essentially no sulfonic acid or sulfonate ester functional groups and each B block is a polymer block containing from about 10 to about 100 mol percent sulfonic acid or sulfonate ester functional groups based on the number of monomer units. The film is exposed to water and dried onto a polar or active metal substrate. The laminates do not delaminate in the presence of water and may be used for a variety of applications including energy exchange applications.

    摘要: The anionic polymerization of unsaturated monomers with functionalized initiators having the structure R.sup.1 R.sup.2 R.sup.3 Si--O--A'--Li is improved by selecting A' from the structures --CH.sub.2 --CH.sub.2 --CH.sub.2 -- (1,3-propyl), --CH.sub.2 --CH(CH.sub.3)--CH.sub.2 -- (2-methyl-1,3-propyl), --CH.sub.2 --C(CH.sub.3).sub.2 --CH.sub.2 --(2,2-dimethyl-1,3-propyl), or --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --(1,8-octyl). This narrow class of polymerization initiators operate at surprisingly higher polymerization temperatures with surprisingly lower amounts of dead initiator than similar initiators wherein A' is --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --(1,4-butyl), --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --(1,5-pentyl), or --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 --(1,6-hexyl).

    摘要: The present invention concerns an improved process for producing an ionomer from an acid group containing polymer. Production of the ionomer requires neutralization of an acid functionality or reaction of anhydride functional groups with a metal ion source to produce a salt. It has been found that metal hydrocarbyls or metal hydrides can be used as the source of metal ions for neutralizing the acid or anhydride functionalities. The reaction can occur in a solvent or in a melt, but is most preferably performed in a solvent.
