摘要： The process consists in the agglomeration of fine particles of superabsorbent polymer, carried out by introducing an aqueous solution of monomer into a slurry of aqueous polymer dispersed within a hydrocarbon liquid, this introduction being performed directly at the temperature and in conditions of polymerization of the monomer. A superabsorbent product is thus obtained in a very good yield, in the form of aggregates of particles such that the fraction passing through a 100-micron screen is less than 1%.

摘要： The invention relates to a process for preparing a composite tubular article consisting of a vulcanized elastomer containing carboxylic acid or dicarboxylic acid anhydride functional groups, which is used in combination with a thermoplastic elastomer containing polyamide blocks. The composite tubular article is prepared such that it consists of an inner layer of thermoplastic elastomer containing polyamide blocks sheathed by extrusion at an appropriate temperature with an elastomeric composition comprising a synthetic or natural elastomer containing carboxylic acid or dicarboxylic acid anhydride functional groups, a crosslinking system and optionally various adjuvants and fillers. Optionally, an innermost layer consisting of a thermoplastic with good liquid-barrier properties is present. The composite tubular article obtained is vulcanized, preferably at a temperature of between -5.degree. C. and +30.degree. C. in relation to the Vicat point of the said thermoplastic elastomer containing polyamide blocks. This process produces composite tubular articles exhibiting excellent properties, particularly of flexibility and of peel strength of the outer layer. The invention also relates to a process for preparing petrol pipes consisting of such articles in which the inner face of the thermoplastic tube is coated with a polymer for protection against liquids and preferably against fuels.

摘要： The present invention relates to thermoplastic polyamides and to thermoplastic elastomers based on polyamide with improved thermomechanical performance. They are obtained by grafting along the polymer chain with alkoxysilanes having at least one unsaturation, and especially vinyltrialkoxysilanes of formula CH.sub.2 .dbd.CH--Si--(OR).sub.3 where R represents an alkyl or an alkoxy-substituted alkyl group. The weight ratio of the silane to polyamide in the grafted polymer is generally between 0.1 and 5%. These grafted polyamides may be crosslinked by hydrolysis in steam at 100.degree. C. or by contact with water. The grafted and optionally crosslinked polyamides may be used for producing molded or extruded articles, such as tubes, jackets, single-layer and multilayer films and complex parts, and powder for coating substrates.
