A method for making a polymer comprising the step of synthesizing a polymer by employing a chain transfer agent having the formula (II)
where X and Y are independently selected from oxygen, sulfur, and fully-substituted nitrogen where R1 and R2 are independently selected from hydrogen, halogen, or an organic group, with the proviso that at least one of R1 or R2 be hydrogen or halogen, R3 is an organic group R4 and R5 are independently selected organic groups, with the proviso that R3 is not hydrogen.
一种制备聚合物的方法,包括通过采用具有公式(II)的链转移剂合成聚合物的步骤,其中X和Y分别从氧、
硫和全取代氮中独立选择,其中R1和R2分别从氢、卤素或有机基团中独立选择,但至少其中之一为氢或卤素,R3是有机基团,R4和R5是独立选择的有机基团,但要求R3不是氢。
