The present invention provides a polymerizable phosphoric acid ester derivative having the following formula (A):
wherein
Z is COOR1, COSR1, CON(R1)2, CONR1R2, CONHR1, or CN,
R1 and R2 independently are a hydrogen atom, a substituted or unsubstituted C1 to C18 alkyl group optionally substituted by a C3 to C8 cycloalkyl group, a substituted or unsubstituted C3 to C8 cycloalkyl group, a substituted or unsubstituted C4 to C18 aryl or heteroaryl group, a substituted or unsubstituted C5 to C18 alkylaryl or alkylheteroaryl group, or a substituted or unsubstituted C7 to C30 aralkyl group, whereby two R1 residues may form together with the N-atom to which they are bonded a 5- to 7-membered heterocyclic ring which may contain beside said N-atom a further nitrogen atom or an oxygen atom, and whereby the substituted groups may be substituted by 1 to 5 C1 to C5 alkyl group(s);
a is an integer of from 1 to 10, preferably 1 to 5;
b is an integer of from 1 to 10, preferably 1 to 5; and
R represents an organic residue containing a + b carbon atoms selected from primary and secondary aliphatic carbon atoms, secondary alicyclic carbon atoms, and aromatic carbon atoms, each of said carbon atoms linking a phosphate or 2-(oxa-ethyl)acryl derivative group.
本发明提供了具有以下结构式(A)的可聚合磷酸酯衍生物:其中Z为COOR1、COSR1、CON(R1)2、CONR1R2、CONHR1或CN;R1和R2独立地为氢原子、经过取代或未经取代的C1至C18烷基,可选地经过C3至C8环烷基取代,经过取代或未经取代的C3至C8环烷基,经过取代或未经取代的C4至C18芳基或杂环芳基,经过取代或未经取代的C5至C18烷基芳基或烷基杂环芳基,或经过取代或未经取代的C7至C30芳基烷基,其中两个R1残基可以与它们结合的N原子一起形成一个5-至7-成员杂环,该杂环除了含有所述的N原子外,还可以含有另一个氮原子或一个氧原子,取代基可以经过1到5个C1至C5烷基的取代;a为1至10的整数,优选为1至5;b为1至10的整数,优选为1至5;R代表一个含有a + b个碳原子的有机残基,选择自主要和次要脂肪碳原子、次要脂环碳原子和芳香碳原子,其中每个碳原子连接一个磷酸酯或2-(氧乙基)丙烯酰衍生物基团。
