Water compatible sterically hindered alkoxyamines and hydroxy substituted alkoxyamines

摘要

Sterically hindered alkoxyamine and hydroxy substituted alkoxyamine stabilizer compounds are made water compatible via certain backbones with affinity towards water. The sterically hindered amines are for example of the formula where for example E and E' are 2-hydroxycyclohexyloxy, 2-hydroxy-2-methylpropoxy, benzyloxy, methoxy, propoxy, hexyloxy, heptyloxy, octyloxy or cyclohexyloxy, Rx is for example -NH2<+>CH2CH2OH Cl<->, -NH3<+->OAc, =NOH, -NHCH(CH3)COO<->K<+>, -NHCH2CH2N(CH3)2<+->OAc, -NHCH2CH2SO3<-K><+>, -NHCH(COO<->K<+>)CH2CH2SCH3, -NHCH2COO<->K<+>, -OCH(CH3)COO<->K<+>, -OCH2CH2N(CH3)2<+->OAc, -OCH2CH2SO3<->K<+>, -OCH(COO<->K<+>)CH2CH2SCH3 or -OCH2COO<->K<+>, and where R5 comprises repeating units of -(OCH2CH2)-, -(OCH2CH2(CH3))-, -(CH2CHCOOH)-, -(CH2C(CH3)COOH)-, -(CH2CHCOOCH3)-, -(NHCH2CH2)-, -(CH2<
