    摘要: The present invention relates to a process for preparing isocyanate homopolymers containing uretdione groups, in which the phosphinoboron compound of formula (I) are used as catalysts to catalyze the homopolymerization reaction of raw isocyanates, thereby obtaining a solution of isocyanate homopolymers having uretdione groups, then separating the solution and thus obtaining the isocyanate homopolymers containing uretdione groups. The isocyanate homopolymers containing uretdione groups prepared by this process have a high amount of the uretdione groups, wherein the dependence of the amount on the conversion rate of raw isocyanates is significantly ameliorated, with low chromaticities.

    摘要: Disclosed are salts of nucleoside analogs and methods of forming the salts. An anion of a nucleoside analog is paired with a permanent counter cation to form a salt that has decreased melting point and increased aqueous solubility compared to the nucleoside compound prior to the salt formation. Also a cation of a nucleoside analog is paired with a permanent counter anion to form a salt that has decreased melting point and increased aqueous solubility compared to the nucleoside compound prior to the salt formation. The nucleoside analog in some embodiments has therapeutic activity such as antiviral. The permanent counter cation or anion in some embodiments has bioactivity such as antibacterial or being a vitamin.
