Chain‐end free volume theory is extended for studying the glass‐transition temperature ( T g ) as a function of conversion in hyperbranched polymers. T g is found to have a non‐linear inverse relationship to the molecular weight for polymers obtained by self‐condensing vinyl polymerization (SCVP). During the monomer conversion process, T g decreases with the increase in molecular weight ( P ) in the low conversion range, then levels off in the high conversion range.
