Abstract

The compatibility of high-density polyethylene (HDPE) and nitrile-butadiene rubber (NBR) blends were examined by ultrasonic velocity measurement. Results reveal that, introducing a small amount of NBR into HDPE could greatly elevate the matrix toughness. The NBR are derived from the copolymerization of butadiene and acrylonitrile, and the strong polarity of acrylonitrile is able to result in incompatibility of HDPE and NBR. From the experimental data, it is found out that the ultrasonic velocity measurement was useful in characterizing the ductile-brittle transition in polymer blends.
