摘要： There is a procedure for polymerisation in solution for the production of polymers. The procedure has the following steps: (A) continuously feeding one or more monomers, one or more solvents in a quantity comprised between 70% and 90% by weight with respect to the reagent mixture, and a catalytic system, to a first stirred reaction volume, wherein a single mixing cell is formed, in which the polymerisation begins, until a conversion is attained that varies from 20% to 70% with respect to the final conversion achieved and (B) proceeding the polymerisation in at least one second stirred reaction volume connected in series to the first reaction volume, in which two or more mixing cells are formed, at the outlet of which the final conversion of the monomer is attained. In the first reaction volume, the average residence time of the reagent mixture varies within an interval ranging from 10% to 25% with respect to the average residence time of the entire reaction volume.

摘要： The present invention relates to a solidification process of the natural rubber latex by means of polyquaternary polymers.
The process of the present invention has the advantage to not require the addition of acids and/or salts, with an evident saving in terms of cost for the reagents. Furthermore, in such a way neither the neutralization step of the rubber nor the treatment of the processing water before their disposal are required.
The process of the present invention is suitable both for the continuous and batchwise embodiment, with evident advantages as far as its industrial application is concerned.

摘要： A method for synthesizing regioregular polyesters, starting from asymmetric diols, may provide the polymer ordered structure and advantageous physical-chemical properties. Such methods can make it is possible to obtain regioregular polyesters having high glass transition temperatures Tg and crystalline properties. In the case in which the asymmetric diols are used in a pure enantiomeric form, with respect to the chiral carbon bound to the secondary hydroxyl, through the above-mentioned method it is possible to obtain regioregular and stereoregular polyesters, which may have thermal and crystalline properties further ameliorative with respect to non-chiral regioregular polymers.

摘要： Process for preparing a random butadiene-isoprene copolymer having a high content of cis-1,4 units comprising copolymerizing butadiene and isoprene, in the presence of at least one organic solvent, and a catalytic system prepared in situ comprising: (a1) at least one neodymium carboxylate soluble in said organic solvent, containing a variable amount of water, the H2O/Nd molar ratio being between 0.001/1 and 0.50/1; (a2) at least one aluminum alkyl compound; (a3) at least one aluminum alkyl compound containing at least one halogen atom. The random butadiene-isoprene copolymer having a high content of cis-1,4 units obtained from the abovementioned process may be advantageously used in a number of applications ranging from the modification of plastics [for example, obtainment of high impact polystyrene (HIPS)], to the production of tires, in particular the production of tire treads and/or of tire sidewalls.

摘要： The invention relates to a process for producing olefins from alcohols by means of catalytic dehydration. More in particular, the present invention relates to a process for producing at least one olefin by dehydrating at least one alcohol having a number of carbon atoms comprised between 2 and 6, preferably comprised between 2 and 4, more preferably at least one alcohol having a number of carbon atoms of 3, even more preferably 2-propanol, in the presence of a catalytic material comprising at least one large pore zeolite in acid form, or predominantly acid form, preferably selected from the group consisting of zeolites having BEA structure, MTW structure and mixtures thereof, and preferably at least one inorganic binder, more preferably alumina. Preferably, the olefin has the same number of carbon atoms as the starting alcohol. Furthermore, preferably the olefin does not contain conjugated double bonds and more preferably the olefin is a mono-olefin. Subject matter of the present invention is also the use of the aforementioned olefin in an alkylation process of aromatic hydrocarbons, in particular the use of propylene for alkylating benzene to provide cumene. The aforementioned cumene can be used in an integrated process for preparing phenol and acetone, in accordance with the Hock method, wherein acetone can be reduced to 2-propanol, to be recycled to the process of the invention to obtain propylene again.
