摘要： An N-vinyl amide polymer is disclosed. The N-vinyl amide polymer is a reaction product of: a monomer component comprising an N-vinyl amide; and a chain transfer agent of the formula:






wherein each occurrence of R1 is independently a C1-20 alkylene, a C1-20 heteroalkylene, a C3-20 cycloalkylene, a C3-20 heterocycloalkylene, a C6-20 arylene, or a combination thereof, and R1 is substituted or unsubstituted; R2 is a divalent or multivalent organic group having 2 to 40 carbon atoms; and n is at least 2.
