    Abstract: An electrorheological fluid is prepared from a hydrophobic liquid medium and a dispersed particulate phase of (i) a polar solid material which is capable of exhibiting electrorheological activity in the presence of a low molecular weight polar material and (ii) a non-cellulosic polymeric material having a solubility parameter of about 15 to about 50 (MPa).sup.1/2 and exhibiting substantially no electrorheological activity in the absence of a low molecular weight polar material. The fluid optionally contains a low molecular weight polar activator. The fluid has good electrorheological performance over a broad temperature range.

    Abstract: The novel polymers of the present invention are prepared by graft polymerization of at least one aromatic nitrogen-containing monomer onto an amino-substituted polymer (e.g., an ethylene alpha-olefin interpolymer substituted by primary amino or secondary amino groups). Preferred aromatic nitrogen-containing moieties are illustrated by aniline, and preferred amino-substituted interpolymers comprise amino-substituted ethylene propylene norbornene terpolymers. The polymers of this invention are oil soluble and are useful as dispersant and antioxidant additives in oleaginous compositions and are further useful in electrical, textile and other applications.
