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-hydroxycydohexyloxy, 2-hydroxy-2-methylpropoxy, benzyloxy, methoxy, propoxy, hexyloxy, heptyloxy, oclyloxy or cyclohexyloxy, Rx is for example -NH2+CH2CH20H Cl-, -NH3+ -OAc, =NOH, -NHCH(CH3)COO-K+,- NHCH2CH2NH(CH3)2+ -OAC, -NHCH2CH2SO3-K+, -NHCH(COO- K+)CH2CH2SCH3, -NHCH2COO- K+, -OCH(CH3)COO-K+, -OCH2CH2NH(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)-, -(CH2CHOH)-, -(CH2CHCONH2)-or -(CH2CH(NHCOH))-. These compounds are particularly effective in stabilizing aqueous polymer systems against the deleterious effects of oxidative, thermal and actinic radiation. The compounds are effective for example in stabilizing water borne coatings, aqueous inks, aqueous inkjet media and photocured aqueous systems.
通过具有亲水性的特定骨架,使具有立体位阻的烷氧胺和羟基取代的烷氧胺稳定剂化合物与水相容。其中,立体位阻胺的示例为以下公式,其中 E 和 E’ 为 2-羟基环己氧基、2-羟基-2-甲基丙氧基、苄氧基、甲氧基、丙氧基、己氧基、庚氧基、辛氧基或环己氧基,Rx 为例如 -NH2+CH2CH20H Cl-, -NH3+ -OAc, =NOH, -NHCH(CH3)COO-K+,- NHCH2CH2NH(CH3)2+ -OAC, -NHCH2CH2SO3-K+, -NHCH(COO- K+)CH2CH2SCH3, -NHCH2COO- K+, -OCH(CH3)COO-K+, -OCH2CH2NH(CH3)2+ -OAC, -OCH2CH2SO3-K+, -OCH(COO- K+)CH2CH2SCH3 或 -OCH2COO-K+,R5 包括重复单元 -(OCH2CH2)-, -(OCH2CH2(CH3))-,-(CH2CHCOOH)-, -(CH2C(CH3)COOH)-, -(CH2CHCOOCH3)-, -(NHCH2CH2)-, -(CH2CHOH)-, -(CH2CHCONH2)- 或 -(CH2CH(NHCOH))-. 这些化合物在稳定水性聚合物体系抵抗氧化、热和光辐射的有害影响方面特别有效。这些化合物例如在稳定水性涂料、水性油墨、水性喷墨介质和光固化水性系统方面非常有效。
