A new quantitative thermal analysis technique was attempted on ABS and Noryl‐type polyblends. A particular component within a polyblend was identified by its glass transition temperature and the amount of the component was determined from the increase in specific heat at the glass transition temperature. Two commercial Noryl resins were determined to be blends of high impact polystyrene and polyphenylene oxide in 47‐47 and 69‐17 proportions by weight, respectively. Polystyrene appears to be cosoluble with polyphenylene oxide without the formation of any complex. The PS‐PPO polyblends yield single sharp glass transitions which are a function of concentration.
