摘要:A process for a double stage convergent synthesis of a polymeric polyalcohol substantially and preferably built up from polyester units and composed of a monomeric or polymeric core to which at least one hyperbranched dendritic branch (dendron) consisting of a number of branching generations is added. The branching generations comprise a polymeric or monomeric branching chain extender having three reactive functions of which two are hydroxyl groups and one is a carboxyl group. The two hydroxyl groups of the branching chain extender is in a first step ketal protected by reacting said two hydroxyl groups with a ketal. A second step includes protection of the carboxyl group of said branching chain extender. The ketal protected branching chain extender and the carboxyl protected chain extender are then employed for repeated addition in a number of step yielding a predetermined number of branching generations. The thus synthesized dendron is finally added to a core having reactive hydroxyl or epoxide groups and the ketal protected hydroxyl groups are optionally deprotected.

摘要:The present invention describes a process for the synthesis of S-nitrosothiols and the subsequent incorporation of these compounds in hydrophilic macromolecular compositions. By the process described herein, the S-nitrosothiols are synthesized in a device (FIG. 2 ) in a first step from the S-nitrosation reaction of their respective precursor thiols (A), promoted by a mechanical action that puts the thiols in contact with the nitrous acid formed from nitrite anions in acidic medium (B), and in a second mechanical operation, the freshly formed S-nitrosothiols are incorporated in an application vehicle (C) based on hydrophilic macromolecular compositions that increases their thermal stability. Therefore, the process under consideration combine the pre-application synthesis of S-nitrosothiols with their subsequent incorporation in delivery vehicles, with provide a relative stabilization of the S-nitrosothiols for sufficient periods so that the formulations prepared by this process may be stored in a domestic refrigerator during its time of use in its several possible applications.
