The effect of the distance between neighboring vinyl groups on template polymerization

Intra-molecular polymerization of methacrylate type multi-vinyl monomer of Noria (Noria-MVM) was investigated from the viewpoint of the structure of Noria-MVM. Noria-MVM was polymerized by atom transfer radical polymerization (ATRP) with different reaction time, temperature, and monomer concentration. Polymerized sequences were derived from polymerized Noria-MVM by hydrolysis and methylation. The degree of polymerization (DP) of polymerized sequence was determined by matrix-assisted laser desorption/ionization time-of-flight mass (MALDI-TOF mass) analyses. The DP values were odd value in a range of 3–23. The distance from radical to the next vinyl group was influenced by the structure of Noria. When the distance was shorter than 5 Å, the polymerization did not terminate. When the distance was longer than 5 Å, the termination tended to occur.
