PHENOL TERMINATED DIESTER COMPOSITION AND CURABLE COMPOSITIONS CONTAINING SAME

摘要

The present invention is directed towards: non-liquid crystalline phenol-terminated diester compositions which may be liquids or solids and crosslinkable formulations containing a mixture of the phenol terminated diesters and an amino crosslinking agent. These diesters are characterized by the structure of formula (1). Also within the scope of the present invention are crosslinkable formulations comprising a mixture of amino crosslinking agent and phenol terminated diesters based on polyester diols containing carbonate and groups of aliphatic and aliphatic/aromatic polycarbonates containing carbonate and groups characterized by structure (2). The invention is also directed to a single stage direct esterification or multi stage esterification processes for producing the aforementioned diesters of formula (I) either with or without the use of esterification catalysts.
