20100032629 | Adhesive composition containing carbon nanotubes and a copolyamide - The present invention relates to a composition containing: (a) carbon nanotubes and (b) at least one copolyamide capable of being obtained from at least two different starting products chosen from: (i) the lactames, (ii) the aminocarboxylic acids and (iii) equimolar quantities of diamines and dicarboxylic acids. | 02-11-2010 |
20100105812 | COPOLYAMIDE, COMPOSITION CONTAINING SUCH COPOLYAMIDE AND USE THEREOF - The invention relates to a copolyamide containing at least two patterns (monomers) and of the following general formula A/(Cz diamine)·(Cw diacid) in which: z is the number of carbon atoms of the diamine and w is the number of carbon atoms of the diacid; and A is selected from a pattern obtained from an amino acid and a pattern of the general formula (Cx diamine)·(Cy diacid) | 04-29-2010 |
20110135860 | BLENDS OF TRANSPARENT AMORPHOUS POLYAMIDES BASED ON DIAMINES AND ON TETRADECANEDIOIC ACID AND SEMICRYSTALLINE POLYAMIDES - The present invention relates to a transparent amorphous polyamide which results from the condensation of at least one diamine chosen from aromatic, arylaliphatic and cycloaliphatic diamines, of tetradecanedioic acid or of a mixture comprising at least 50 mol % of tetradecanedioic acid and at least one diacid chosen from aliphatic, aromatic and cycloaliphatic dicarboxylic acids. The invention also relates to a composition comprising, by weight, 1 to 100% of the preceding polyamide and 99 to 0% of a semicrystalline polyamide. The invention also relates to the objects composed of the composition of the invention, such as panels, films, sheets, pipes, profiles or objects obtained by injection moulding. The invention also relates to objects covered with a transparent protective layer composed of the composition of the invention. | 06-09-2011 |
20110288194 | POLYAMIDE AND BIORESOURCED REINFORCEMENT COMPOSITIONS HAVING IMPROVED MECHANICAL PROPERTIES - One subject of the present invention is a composition that combines at least one polyamide having at least one MXD entity, MXD denoting meta-xylylenediamine or a mixture of meta-xylylenediamine and of para-xylylenediamine, with a bioresourced reinforcement. The invention also relates to the conversion of these compositions, by injection moulding or extrusion, into objects that have good mechanical properties, said objects corresponding to technical application specifications such as may be found, for example, in the automotive industry, construction, sport and in electrical or electronic fields. | 11-24-2011 |
