PVC compounds containing CaCO3 filler and plasticizers were prepared w
ith or without a trifunctional acrylic crosslinking agent and irradiat
ed by Co-60 gamma-rays under air or nitrogen atmosphere. The samples w
ithout crosslinking agent did not respond to irradiation. The mechanic
al properties of the other samples such as tensile strength, yield str
ength and % elongation showed a great sensitivity to irradiation. Lowe
r values of Young's modulus were observed for samples irradiated in ai
r compared with samples irradiated in nitrogen indicating the effect o
f atmosphere in the range of irradiation studied.
