Efficiency of liquid tin(ii): N -alkoxide initiators in the ring-opening polymerization of l-lactide: Kinetic studies by non-isothermal differential scanning calorimetry

Novel soluble liquid tin(ii) n-butoxide (Sn(OnC4H9)2), tin(ii) n-hexoxide (Sn(OnC6H13)2), and tin(ii) n-octoxide (Sn(OnC8H17)2) initiators were synthesized for use as coordination-insertion initiators in the bulk ring-opening polymerization (ROP) of l-lac

PROCESS FOR THE PREPARATION OF LIQUID TIN(II) ALKOXIDES

This invention describes the synthetic process of producing liquid tin(II) alkoxides for use as either reagents in the synthesis of lactide or as initiators in the polymerization of cyclic ester monomers to yield biodegradable polyesters. The synthetic process employs anhydrous tin(II) chloride dissolved in n-heptane and mixed with dry diethylamine. Alcohols, ROH, in which the R groups are n-C4H9, n-C6H13, and n-C8H17 are added to the reaction mixture and stirred for 12 hours. The reaction mixture isthen filtered under nitrogen or argon before being evaporated to dryness to yield the three tin(II) alkoxides, namely: tin(II) n-butoxide, tin(II) n- hexoxide, and tin(II) n-octoxide. All three tin(II) alkoxides are viscous, dark yellow liquids which are highly soluble in most common organic solvents. Furthermore,they can all be stored under an inert atmosphere for long periods without any significant change in their vi nd therefore in their effectiveness as rea ents/initiators.

Electrosynthesis of tin(II) alkoxides

The anodic dissolution of tin metal in absolute alcohols yields oxoalkoxides with the general formula Sn6O4(OR) 4 (R = Me (1), Et (2), i-Pr (3)) and orthoalkoxides with the general formula Sn(OR)2 (R = n-Bu (4),
