摘要: A copolymer containing repeat units formed from the monomers (I) and (II), wherein each R1, if present, is independently hydrogen or hydrocarbyl; r is 0, 1 or 2; s is either 2 or 3; R2–R4 are each independently hydrogen or hydrocarbyl; R5 and R6 are each independently hydrogen, halo or hydrocarbyl; Pd− is the anion formed by loss of a proton from a proton donating group Pd—H; Z is either a bond or hydrocarbyl; R7 and R8 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
