This invention discloses a process for producing a polymer by controlled polymerization which comprises polymerizing at least one monomer in the presence of a free radical control agent of the structural formula: (Z)-(R
1
)
n
, wherein n represents an integer from 1 to about 6; wherein Z represents an aromatic or aliphatic moiety containing from 1 to about 20 carbon atoms; wherein R
1
represents a moiety of the structural formula:
wherein R
2
represents a moiety selected from the group consisting of alkyl groups, alkenyl groups, alkynyl groups, aryl groups, heteroaryl groups, and alkaryl groups; wherein the alky groups, alkenyl groups, alkynyl groups, aryl groups, heteroaryl groups, and alkaryl groups can be substituted, unsubstituted, linear, branched or cyclic; and wherein Ar represents a p-alkoxyphenyl group having an alkoxy moiety that contains from 1 to 8 carbon atoms. For instance, the free radical control agent can be of the structrul formula:
wherein R
2
represents a moiety selected from the group consisting of alkyl groups, alkenyl groups, alkynyl groups, aryl groups, heteroaryl groups, and alkaryl groups; wherein the alky groups, alkenyl groups, alkynyl groups, aryl groups, heteroaryl groups, and alkaryl groups can be substituted, unsubstituted, linear, branched or cyclic; and wherein Ar represents a p-alkoxyphenyl group having an alkoxy moiety that contains from 1 to 8 carbon atoms.
该发明揭示了一种通过受控聚合生产聚合物的方法,其中包括在自由基控制剂的存在下聚合至少一种单体,所述自由基控制剂的结构式为:(Z)-(R1)n,其中n表示一个整数,范围从1到约6;其中Z代表含有1到约20个碳原子的芳香或脂肪基;其中R1代表结构式的一个基团:其中R2代表从烷基基团、烯基基团、炔基基团、芳基、杂环芳基和烷芳基组成的基团;其中烷基基团、烯基基团、炔基基团、芳基、杂环芳基和烷芳基可以是取代的、未取代的、直链的、支链的或环状的;其中Ar代表具有包含1到8个碳原子的烷氧基团的p-烷氧基苯基团。例如,自由基控制剂可以是结构式:其中R2代表从烷基基团、烯基基团、炔基基团、芳基、杂环芳基和烷芳基组成的基团;其中烷基基团、烯基基团、炔基基团、芳基、杂环芳基和烷芳基可以是取代的、未取代的、直链的、支链的或环状的;其中Ar代表具有包含1到8个碳原子的烷氧基团的p-烷氧基苯基团。
