LIQUID CRYSTAL POLYMER

The polymer contains a comonomer to which is bonded a radical where X is a chemical bond, O or NR , Y is a chemical bond or -CO-, R is hydrogen or C1-C4-alkyl, and A is a linear or branched C2-C20-alkylene group which may be interrupted by -O- or -NR . The copolymer has very good light fastness, a h...

Beschreibung
Zusammenfassung:	The polymer contains a comonomer to which is bonded a radical where X is a chemical bond, O or NR , Y is a chemical bond or -CO-, R is hydrogen or C1-C4-alkyl, and A is a linear or branched C2-C20-alkylene group which may be interrupted by -O- or -NR . The copolymer has very good light fastness, a high dichroic ratio and high absorption.
