The present invention relates to a novel synthesis route that can be used to access novel statistical, aliphatic-aromatic copolyamides, by means of ring-opening polymerisation and chain-growth polycondensation, as well as to the resulting copolymers.

Route for the synthesis of statistical, aliphatic-aromatic copolyamides, and the resulting statistical, aliphatic-aromatic copolyamides

The present invention relates to a process for preparing a compound having the formula (I), said process comprising the following steps: a) the addition of an oxygen source into a solution of a compound of formula (II), in a water-miscible solvent, b) the addition of a laccase in the solution obtained after step a); and c) the possible recovering of the compound of formula (I) thus obtained. 

Process for preparing biphenyl compounds

The present invention concerns the use of a compound having the following formula (I), for the preparation of a polymer. The present invention also concerns the polymers obtained from polymerization of compound of formula (I), and their processes of preparation. 

Phenolic polymers and preparation processes thereof

Stage I Group 1 metal/porous metal oxide compositions or Stage II Group 1 metal/porous metal oxide compositions are shown to be useful to remove impurities and act as drying agents for various types of solvents and for olefinic monomers used in anionic polymerizations. One important advantage of these compositions is their ability to dry simultaneously solvent and monomers, without inducing a significant polymerization of the latter. Another important characteristic is the capacity of the compositions to be totally inactive toward conventional anionic polymerization which allows them to be left in situ during the polymerization itself.
