    • The invention relates to a process for coating objects using polymer-containing powder coatings which are applied to the surface of the substrate, melted and cross-linked by exposure to UV radiation. The polymers used are copolymers containing the following: (a) at least one monomer of general formula (I) CH2=C(R )-CO-OR , in which R is H or CH3 and R is H, CnH2n+1, n being 1-30, an alicyclic, araliphatic or heterocyclic group or hydroxyalkyl, alkoxyalkyl, glycidyl or aminoalkyl group, or of general formula (II) CH2=C(R )-CO-NR R , in which R is H or CH3, R and R can be identical or different and stand for H, CH2OH or CnH2n+1, n being 1-30, or CH2OR , R being CmH2m+1 and m being 1-12; and (b) at least one copolymerisable ethylenically unsaturated organic compound of general formula (A), in which R' and R'' can be identical or different and stand for H, CpH2p+1, p being 1-6, cycloalkyl, aryl or aralkyl and R''' stands for an acryloyl, methacryloyl, ethacryloyl or cinnamoyl group, this compound being partially replaceable by one or more other copolymerisable ethylenically unsaturated organic compounds different from (a).
    • 本发明涉及一种用于用含有施加到涂基材的表面的粉末涂料的聚合物涂层制品的方法,熔化并通过UV辐射交联的,因为聚合物是(a)的通式中的至少一种单体(I)的共聚物 CH 2 = C(R <1>) - CO-或<2> [R <1> = H或CH 3和R <2> = H,为C n H 2n + 1个,其中n = 1〜30,脂环族,芳脂族或杂环基团 羟烷基,烷氧基烷基,缩水甘油基或氨基烷基,或通式(II)CH 2 = C(R <1>) - CO-NR <3> [R <4>其中R <1> = H或CH 3和 其中R <3>和R <4>对于彼此可以相同或不同,为H,CH 2 OH或为C n H 2n + 1个,其中n = 1〜30或CH 2 OR,其中R <5> = C米ħ2M + 1,其中m = 1到<5> 12设置; 和(b)至少一种可共聚的通式的烯属不饱和有机化合物(A),其中R“和R”“可以是相同的或彼此不同,它们是H,C P H 2P + 1,其中p = 1〜6,环烷基,芳基 或芳烷基,R“”“是一个丙烯酰基,甲基丙烯酰基,肉桂酰基或Ethacryloyl-是,所述化合物可通过一个或多个其它的(a)中使用不同的可共聚的烯属不饱和有机化合物的部分代替。
