<p>Described herein is a melt-processable block copolyesterimide comprising the repeating units (I), (II) and (III) and, optionally, a repeating unit (IV), wherein (I) is a repeating unit of formula (I) wherein R is an aliphatic polyether chain and/or a polysiloxane chain; (II) and (III) are repeating units of formulaes (II) and (III) wherein Z is hydrogen, alkyl, alkoxy, aryl, halogen and w is zero or one; and (IV) is a repeating unit of formula (IV), wherein Z' is hydrogen, alkyl, alkoxy, aryl or halogen and the phenylene ring is substituted in m- or p-position. The repeating unit of formula (I) is present in an amount of 5 to 50 mole-%, the repeating unit of formula (II) is present in an amount of 10 to 80 mole-%, the repeating unit of formula (III) is present in an amount of 5 to 50 mole-% and the repeating unit of formula (IV) is present in an amount of 0 to 45 mole-% of the block copolyesterimide. The polymer according to the invention has liquid crystalline properties and it can be used as thermoplastic elastomer component of polymer compounds.</p> |
