The polymerization afforded poly(4-vinylbenzyl glucoside peracetate) having TEMPO moieties on both sides of the chain ends, 3, with a molecular weight (Mw,SLS) of 8500, a polydispersity index (Mw/Mn) of 1.09, and an average degree of polymerization of the 1 unit (x) of 17. Styrene (St) was polymerized with 3 in chlorobenzene at 125 °C (St/chlorobenzene=1/2, w/w).
High-performance inulin is manufactured to remove the shorter chain molecules so that it has an average degree of polymerization of 25 (Niness, 1999).
The high weight average degree of polymerization but low number average degree of polymerization at the critical point should attribute to the reason that the larger the species formed in the reaction system, the faster its growth.
In the former fraction, the average degree of polymerization (¯¯¯¯¯¯¯¯DPn) of procyanidins was 7.0, while only oligomer phenols with DPn¯= 3.0 were found in the OW fraction.
Similarly, the average degree of polymerization (DP) increased from 3 DPA (12.3) to 12 DPA (15.0), and then did not differ significantly up to 30 DPA (15.0).
The average degree of polymerization (DP) of the PAEM block was varied among 19, 39, and 75, with nearly uniform distribution.
