摘要： Particulate inorganic or mineral materials, are surface modified by treatment with an organic aluminium derivative of the formula (RO)nAlR''3 n where R is an aliphatic or aromatic hydrocarbyl radical containing 1 - 12 carbon atoms; R'' is a substituted or unsubstituted, saturated or unsaturated carboxylate radical (R''''CO2-) or oxy radical (R''''''O-) or a mixture of such radicals, where R'''' and R'''''' are aliphatic, alicyclic, aromatic, aralkyl or heterocyclic radicals and R'''' contains 1 to 36 carbon atoms and R'''''' contains 6 to 25 carbon atoms with the proviso that R'''''' is not identical with R; and n has the value 1 or 2. The thus modified particles have a layer, chemically bonded to their surfaces, which comprises at least one oxyaluminium derivative of the carboxylate or oxy radical, in which at least one of the radicals R'''' and R'''''' is oriented to provide a hydrobic and oleophilic surface for the particle. The products show improved dispersability in organic liquid and plastics systems and confer improved mechanical properties on plastics containing the materials as fillers.

摘要： The invention provides a method for promoting the curing reactions of an acetylenic oligomer or polymer, characterised in that the oligomer or polymer is cured in the presence of sulfur or an organic sulfur derivative which is capable of lowering the temperature of cure of the oligomer or polymer. The invention also provides a process for producing a poly-imide oligomer or polymer containing an aliphatic or aromatic disulfide moiety which is covalently bound to, and forms an integral part of the oligomer or polymer and which is capable of lowering the temperature of cure of the oligomer or polymer, characterised in that a suitable amount of a diamino-disulfide or dianhydride-disulfide, or any suitable derivative or precursor thereof, is introduced into the mixture of aromatic diamines, tetracarboxylic dianhydrides, and the phenylethynyl-substituted amine or anhydride normally used for the preparation of the oligo-imide.

摘要： Oligomers are produced from unsaturated monomers. They contain terminal unsaturation and have a degree of polymerization of from 2 to 200. These oligomers are produced by the free radical polymerization of unsaturated monomers using as an initiator and/or chain transfer agent in the process a transition metal complex comprising a metal cation and at least one chelating agent, said transition metal complex being generally in accordance with formula (I), wherein M is a transition metal ion which can form hexa- or penta-coordinated structures and, when complexed in this manner, has two or more readily interconverted adjacent valence states, R is hydrogen or an organic group or a transition metal complex derived from formula (I) and L is a ligand for controlling the stability and electron transfer properties of the transition metal complex and consists of an electron pair donor (Lewis base) capable of coordination with the metal ion.
