The glass‐transition temperature ( T g ) of the poly(vinylidene fluoride) (PVF 2 )‐poly(methyl acrylate) (PMA) blends increase with aging time. The T g versus log(time) plots are straight lines whose slope values depend on the head to head (H–H) defect content of PVF 2 samples and on the composition of the blends. The values of polymer–polymer interaction parameters (χ) increase with an increase in the H–H defect of PVF 2 for a fixed composition of the blend. Consequently, the T g of the blend decreases with an increase in the H–H defect of the PVF 2 sample. However, after aging for longer times this decrease of the T g with H–H defects is lower than those of the unaged blends. The possible reasons are discussed. © 2000 John Wiley & Sons, Inc.
