A novel macro-RAFT emulsifier was synthesized with S, S’-bis(α, α’-dimethyl-α”-acetic acid)-trithiocarbonate (BDATT), M13-10 (self-made emulsifier) and acrylate monomer, which was further used to prepare surface sizing agent. On the other hand, M13-10 was synthesized with iso-tridecanol polyoxyethylene ether, sodium methoxide and sulfamic acid as the starting materials. The hydrophilicity of macro-RAFT emulsifier and the performance of surface sizing agent were affected by BDATT used as the chain transfer agent and M13-10 as the hydrophilic monomer. So, the CMC and HLB of the emulsifier prepared with different M13-10 content and BDATT content, were compared, as well as the particle size of the prepared surface sizing agent, and the cobb, bursting resistance, tensile resistance, folding endurance and roughness of paper sized. The results reveal that surface sizing agent with macro-RAFT emulsifier of which the amount of M13-10 is 7 w% and the amount of BDATT is 2.5 w% demonstrates the best sizing effect on paper with the contact angle of 119°, the surface water absorption (cobb) of 48.8 g/m2, the bursting strength of 285 kPa, the folding endurance of 19 and the tensile strength of 59.6 kN/m.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
