Production of organometallic polymers by the interfacial technique. XI. Synthesis of poly(organotin esters) and a study of some associated reaction variables

Polyesters of the form below are prepared by the interfacial method. Isolation procedures are presented and discussed. magnified image Polymer yield is constant as stirring rate, stirring time and nature of the organic solvent are varied. Molecular weight is constant as stirring rate and organic solvent nature are varied. Molecular weight increases as reaction time increases. No correlation is found between polymer molecular weight and polymer softening range.
