POLYMER COMPRISING REPEATING UNITS CONSISTING OF A SUBSTITUTED PYRROLE RING AND PRODUCTS OBTAINED BY COMBINING SAID POLYMERS WITH CARBON ALLOTROPES
The present invention relates to a polymer comprising repeating units consisting of a substituted pyrrole ring. In particular, the repeating units consist of substituted pyrrole containing polar groups capable of interacting with carbon allotropes such as carbon nanotubes, graphene or nanographites, in order to improve the chemical-physical characteristics of the allotropes mainly by increasing their dispersibility and stability in liquid media and in polymer matrices. The invention also relates to products of addition of these polymers with carbon allotropes in order to obtain easily dispersible macromolecules.

Process for making polyether alcohols having oxyethylene units by polymerization of ethylene carbonate in the presence of double metal cyanide catalysts
Ethylene carbonate is polymerized by itself or together with another cyclic monomer such as 1,2-propylene oxide in the presence of a double metal cyanide catalyst. Most of the ethylene carbonate adds to the chain to form a terminal carbonate group, which decarboxylates to produce a hydroxyethyl group at the end of the polymer chain. The polymerization of more ethylene carbonate onto the chain end results in the formation of poly(ethyleneoxy) units. Therefore, the process provides a method for making poly(ethyleneoxy) polymers without the need to polymerize ethylene oxide. The process is useful for making polyethers that are useful as water-absorbable polymers, surfactants and as raw materials for polyurethanes. The process is also useful for increasing the primary hydroxyl content of a polyether.
