    摘要: The present invention relates to novel compositions comprising (a) anionic block copolymers having at least two blocks of a mono alkenyl arene and at least one block of a conjugated diene and mono alkenyl arene having a specific arrangement of the monomers in the copolymer block, and (b) tailored softening modifiers have a particular structure that results in a surprising improvement in properties for the composition. Also included are processes for the manufacturing such novel compositions and various end-uses and applications for such compositions.

    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.

    摘要: A blend of a modified thermoplastic block polymer of a conjugated diene and an alkenyl arene with an extender resin compatible with the conjugated diene block is described herein. The block copolymer is first selectively hydrogenated and thereafter modified by grafting carboxyl functional groups primarily in the alkenyl arene blocks.
