| 摘要 |
<p>The invention is related to polyester dendrimers of a polyol with 2-64 reactive hydroxyl groups wherein ester functions are formed using alternating sequences of haloacetyl halide and alkali metal salt of a carboxylate. Said polyester dendrimers are prepared via a two step process from a polyol and a haloacetyl halide (step 1) and subsequent reaction with an alkali metal salt of a carboxylate (step 2). Further, the invention is directed to the use of said polyester dendrimers as cross linkers in polymers and gels, active components in glues and coatings, matrix material in inorganic or organic or bio-composites as well as ionselective complexation agents for analytical and catalysis applications.</p> |
