Novel reactive hot melt structural adhesives comprising urethane oligomer and epoxy mixture in specified ratios. The compositions offer very high shear, peel, and impact strengths, properties of particular value in bonding adherends in an auto body assembly line.

This invention relates to water soluble crayon compositions which are comprised of (i) one or more water soluble block polymers characterized by an ABCBA structure and (ii) a coloring agent, and to crayons produced therefrom. This invention also relates to processes for the production of water soluble crayon compositions and for the manufacture of crayons.

Disclosed is the preparation of organic/inorganic hybrid particles comprising magnesium hydroxide cores and tethered copolymer chains whose composition can be selected to allow dispersion in targeted plastic materials, thereby providing improved mechanical, electrical and flame retardant properties. Processes for preparing the same are also disclosed.

A method of connecting a center contact within a coax connector is disclosed which involves inserting a dielectric sleeve into one end of a coupling member for connecting high frequency coaxial cable so that the center conductor of a cable terminating in the coupling member is received in the inner end of the dielectric sleeve, inserting a center contact member into the other end of the dielectric sleeve a predetermined distance with an insertion tool for press-fitting the same over the cable ce...

An epoxy resin composition for encapsulating semiconductors and semiconductor elements is disclosed. This epoxy resin composition mainly comprises (a) a polyfunctional epoxy compound, (b) a styrene type block copolymer or styrene type block copolymer and liquid rubber, (c) a hardener for the epoxy compound and (d) an inorganic filler.

Combinatorial libraries are disclosed which are represented by Formula I: ##STR1## wherein: ##STR2## is a solid support; T'--L-- is an identifier residue; and --L'--II' is a ligand/linker residue. These libraries contain dihydrobenzopyrans of the formula ##STR3## which interact (i.e., as agonists or antagonists) with .alpha. adrenergic receptors, dopamine receptors, .sigma.-opiate receptors, and K.sup.+ channels and are inhibitors of carbonic anhydrase isozymes. They are useful in the treatment ...

Graft copolymers containing: (1) a phenolic resin; and (2) a poly(alkylene oxide) chain pendant to the phenolic resin, selected such that the graft copolymer has a solubility of no more than about 10 g/L in water, are taught. The graft copolymers are useful in coatings compositions with a curing agent, a solvent, and optionally an epoxy resin. The curable compositions have improved flexibility and/or solvent resistance. They are particularly useful in can coatings.

Curable suspensions of an epoxy resin formulation comprising a) a storage-stable suspension of an epoxy resin and a toughener suspended therein which contains no groups that react with a curable epoxy resin system, b) dicyandiamide, a polycarboxylic acid, a polycarboxylic anhydride, a polyamine, a polyaminoamide, an amino group-containing adduct of an amine and a polyepoxide, a polyol or a catalytically curing hardener, and, as optional components, c) a curing catalyst, conventional fillers or r...

A magnetic composition is disclosed. The composition includes a polymeric mixture and a magnetic material.

A polymer gel composition useful in the fabrication of a vibration damping material comprises a maleated polyalkylene grafted via a grafting agent such as a diamine to a poly(alkenyl-co-maleimide), an epoxy polymer and, optionally, an extender such as a phthalate oil.
