Polymer compositions with adhesive properties comprising:

Polymeric compositions with adhesive properties

Process for modifying a polyolefin grafted with acid or anhydride groups, by at least partial neutralization of these groups with at least one neutralizing agent comprising an organic salt (1) that releases an organic acid (I) during the neutralization, according to which the organic acid (I) derived from the neutralization of the grafted polyolefin is reacted with at least one inorganic salt (2). Modified polyolefin (that can be) obtained by the process described above. Polymeric composition containing (A) at least one polymer, and (B) at least one modified polyolefin (that can be) obtained by the process above. Article comprising the modified polyolefin or the composition described above.

Method for modifying graft polyolefins, compositions and articles comprising polyolefins modified thus

Thermoplastic halogenated polymer compositions characterized by an Rvalue of between 1.1 and 6; process for preparing them; use for the manufacture of films, sheets, panels, foamed tubing, tubes, pipes, foams, bottles or products that are theromoformed and/or moulded; use of the foamed tubing for the sheathing of power cables.

Thermoplastic halogenated polymer compositions, method for preparing same and use thereof

Process for producing polyolefins, comprising the following steps: Polyolefin obtained.

Polyolefins and process for manufacturing them

Polyolefins and method for the production thereof

Propylene polymer containing monomer units derived from at least one functional compound (A) comprising at least two vinyl unsaturations and one or a number of aromatic rings which exhibits a structural stress-hardening.

Propylene polymer, process for obtaining it and use

Thermoplastic composition comprising at least:

Thermoplastic composition, process for its preparation, and use

Process for the synthesis of polyamides by polycondensation in a closed reactor of one or a number of dicarboxylic acids with a diamine compound containing not less than 60 mol % of-m-xylyenediamine, in which all the amount of diamine compound stoichiometrically necessary for the polycondensation reaction is quickly brought into contact with the molten acid, the temperature of the reaction mixture is raised to a value greater than the melting point of the polyamide produced, the pressure is only allowed to rise to a value sufficient to prevent solidification of the reaction mixture and a substantial loss of diamine compound and, at the end of the reaction, the pressure of the reaction mixture is reduced and the polyamide formed is recovered.
