Methods for synthesizing acryloyl-based copolymers, terpolymers

A method for synthesizing an acryloyl-based copolymer, the method comprising:

• (A) providing a free radical initiator with a solution comprising monomeric repeating units, a chain transfer agent, and an organic solvent to form a reaction mixture, in which:
• the monomeric repeating units comprise a first monomeric repeating unit having formula (1a), a second monomeric repeating unit having formula (1b) or (1d), and optionally a third monomeric repeating unit having formula (1c):
• in which:
• R1, R3, R4, and R5 are each independently chosen from divalent C4-C7 aliphatic groups and divalent C4-C7 heteroaliphatic groups, optionally substituted with one or more C1-C6 aliphatic groups, heteroatoms independently chosen from O, N, and S, or combination thereof, where:
• the divalent C4-C7 heteroaliphatic groups of R1, R3, R4, and R5 comprise one or two heteroatoms independently chosen from O, N, and S, and
• the maximum number of heteroatoms in R1, R3, R4, or R5 is two;
• and
• the organic solvent is chosen from monoethylene glycol, ethanol, toluene, or combination thereof;
• and
• (B) initiating a polymerization reaction in the reaction mixture to polymerize the monomeric repeating units, thereby synthesizing the acryloyl-based copolymer.
