A copolymer containing repeat units formed from the monomers (I) and (II), wherein each R
1
, if present, is independently hydrogen or hydrocarbyl; r is 0, 1 or 2; s is either 2 or 3; R
2
-R
4
are each independently hydrogen or hydrocarbyl; R
5
and R
6
are each independently hydrogen, halo or hydrocarbyl; P
d
−
is the anion formed by loss of a proton from a proton donating group P
d
-H; Z is either a bond or hydrocarbyl; R
7
and R
8
are each independently hydrogen, halo or hydrocarbyl; and either (a) A is an electron accepting group and W is either hydrogen or hydrocarbyl, (b) W is an electron accepting group and A is either a bond or hydrocarbyl or (c) both A and W are electron accepting groups. The invention also provides a method for preparing the copolymer by polymerising a mixture of (I) and (II) or their non-ionised precursors, preferably by exposure to ultraviolet radiation. The invention also relates to the uses of the copolymer in adhesive, coating, sealant and stereolithographic compositions.
含有由单体 (I) 和 (II) 形成的重复单元的共聚物,其中每个 R

独立地为氢或烃基;r 为 0、1 或 2;s 为 2 或 3;R
2
-R
4
各自独立地为氢或烃基;R
5
和 R
6
各自独立地为氢、卤代或烃基; P
d
-
是指从质子捐赠基团 P
d
-H;Z 是键或烃基;R
7
和 R
8
各自独立地为氢、卤代或烃基;以及 (a) A 为电子接受基,W 为氢或烃基;(b) W 为电子接受基,A 为键或烃基;或 (c) A 和 W 均为电子接受基。本发明还提供了一种通过聚合(I)和(II)的混合物或它们的非离子化前体来制备共聚物的方法,最好是通过紫外线辐射。本发明还涉及共聚物在粘合剂、涂料、密封剂和立体平版印刷组合物中的用途。
