I found the field of Polymer Science very interesting. Saw the article SnOct(2)-catalyzed and alcohol-initiated ROPs of L-lactide – About the influence of initiators on chemical reactions in the melt and the solid state published in 2021.0. Safety of Benzyl Alcohol, Reprint Addresses Kricheldorf, HR (corresponding author), Univ Hamburg, Inst Tech & Makromol Chem, Bundestr 45, D-20146 Hamburg, Germany.. The CAS is 100-51-6. Through research, I have a further understanding and discovery of Benzyl Alcohol
SnOct(2) (Sn(II) 2-ethylhexanoate) catalyzed ROPs of L-lactide were performed in bulk with eight different alcohols as initiators. The time was varied between 1 h and 24 h for all initiators. For two initiators the temperature was also lowered to 115 degrees C. Even-numbered chains were predominantly formed in all polymerizations at short times, but the rate of transesterification (e.g. even/odd equilibration) and the molecular weight distribution were found to depend significantly on the nature of the initiator. Observed transesterification reactions also continued in solid poly(L-lactide), and with the most active initiator, almost total equilibration was achieved even at 130 degrees C. This means that all chains including those of the crystallites were involved in transesterification reactions proceeding across the flat surfaces of the crystallites. The more or less equilibrated crystalline polylactides were characterized by DSC and SAXS measurements with regard to their melting temperature (T-m), crystallinity and crystal thickness.
