The polymerization of allyl alcohol and allyl acetate in the presence of zinc chloride

Poly(allyl alcohol) Homo- and Block Polymers by Postpolymerization Reduction of an Activated Polyacrylamide

“…1 H NMR analysis (Figure 2a, Figures S1−S3) indicated full reduction to primary alcohols, evidenced by a new resonance at δ = 3.51 ppm corresponding to methylene protons adjacent to the hydroxy groups and integrations consistent with the anticipated allyl alcohol repeat unit. Calculation of M n by end group analysis closely matched the M n predicted from full reduction, and no carbonyls were observed in the 13 C spectrum of the reaction product (Figure 2b, Figure S4). In contrast to polyacrylates, PAA was stable to acidic (pH = 2) and basic (pH = 12) aqueous conditions over multiple days (Figures S5 and S6).…”

“…Poly­(allyl alcohol) (PAA) in particular has attracted interest due to its formal equivalence to hydroxy-functionalized polypropylene . Previous efforts to polymerize allyl alcohol have used Brønsted or Lewis acids to inhibit chain transfer to monomer, resulting in relatively higher molar masses ( M n 5–20 kDa). − These conditions generally require either a) continuous radical generation and reinitiation by γ irradiation which results in significant branching and cross-linking; or b) extended reaction times (7 days) using thermal initiators which results in very low (<5%) yields. Transition metal-catalyzed homopolymerization of allyl alcohol also suffers from side reactions such as chelation of the hydroxy group to the metal center and formation of stable π-allyl species .…”
