alkyl group, an aromatic or heteroaromatic group, a C
3
-C
8
cycloalkyl or C
2
-C

-C
8
cycloalkyl or C
2
-C
7
heterocyclic group; or a —CH

-C
6
alkyl group. At least one of R1 and R2 is a —C(O)R3 group. The polymer may be a homopolymer or a copolymer containing other ethylenically unsaturated monomers. The polymer may be used in a variety of coating compositions such as inks, adhesives, paints and films. Unique monomers where both R1 and R2 are acetoacetyl groups and novel monomers where R2 is an acetoacetyl group are also described.
该规范描述了具有式(I)的单体的各种聚合物:
在式(I)中,R1和R2分别是氢、C1-C24烷基、芳香或杂芳基、C3-C8环烷基或C2-C7杂环烷基、或者—C(O)R3基团,其中R3是C1-C24烷基、芳香或杂芳基、C3-C8环烷基或C2-C7杂环基;或者—CH2—C(O)—R4基团,其中R4是C1-C6烷基。R1和R2中至少有一个是—C(O)R3基团。该聚合物可以是同聚物或含有其他乙烯基不饱和单体的共聚物。该聚合物可用于各种涂料组合物,如油墨、粘合剂、油漆和薄膜。还描述了R1和R2均为乙酰乙酰基团的独特单体以及R2为乙酰乙酰基团的新型单体。
