Calorimetric behavior of methacrylic polymers

Specific heats for poly(methyl methacrylate), poly(diethylaminoethyl methacrylate), poly(cyclohexyl methacrylate), poly(allyl methacrylate), and poly(ethyl acrylate) were measured from 120 to 300°C. with a drop calorimeter. It was found that existing solid‐state theories and equations were unable to...

Description
Summary:Specific heats for poly(methyl methacrylate), poly(diethylaminoethyl methacrylate), poly(cyclohexyl methacrylate), poly(allyl methacrylate), and poly(ethyl acrylate) were measured from 120 to 300°C. with a drop calorimeter. It was found that existing solid‐state theories and equations were unable to correlate the data. The reason advanced was that such theories were developed for crystalline materials, which differed greatly from the amorphous polymers of the present work. A more successful approach was to use a correlation technique originally developed for organic liquids.
