Polyacrylamide is a white powder or small granule with a density of 1.32g/cm3 (23 degrees), a glass transition temperature of 188 degrees, and a softening temperature of nearly 210 degrees. Generally, it contains a small amount of water when it is dried. When it is dried, it will quickly absorb water from the environment. The homopolymer separated by freeze-drying method is a soft, white amorphous solid.
