    Abstract: Activator solid support for metallocenes as catalysts in the polymerization of olefins, characterized in that it consists of a group of support particles for a solid catalytic component, which are formed from at least one porous mineral oxide, the said particles having been modified in order to carry, on the surface, aluminium and/or magnesium Lewis-acid sites of formula: or —Mg—F, the groups coming from a functionalization agent having reacted with —OH radicals carried by the base particles of the support, the functionalization reaction having been followed by a fluorination reaction. The catalytic system according to the invention comprises (a) a metallocene catalyst, which has, if required, been subjected to a prealkylation treatment; (b) a cocatalyst; and (c) an activator solid support for metallocene, as defined above, it being possible for the cocatalyst (b) to be absent if the metallocene catalyst (a) has been prealkylated.

    Abstract: Polymer compositions comprising poly(benzhydrolimide) chains ending with ethylenic unsaturated groups complying with the general formula: ##STR1## wherein Ar is a divalent aromatic radical and R a hydrogen atom or a monovalent hydrocarbon radical. They can be prepared by reacting, under imidation condition, at least one primary diamine with at least one benzydrol 3,3', 4,4'-tetracarboxylic acid, a bis (ortho-acid-ester) or a tetraester of such acid and with an anhydride, an acid-ester or a diester of dicarboxylic cycloaliphatic acid with ethylenic unsaturation. These compositions may be converted to cross-linked polymides by thermal polyemrization. They can be used in particular for manufacturing composite materials, adhesives, molded articles and protective coatings withstanding high temperatures.
