✦ Synopsis

The tan&~ effect of acrylates on radiation vulcanization of natural rubber latex was studied. The noulb, indicate that ac value of crossllnking (Gc) will be higher ht the same radiation dose when a sensitizer etits, and Oc value decreasea with the incriase of radiation dotie (D) conforming to the formula Gc=KD', whets K and a are constants depending on sensitizers. The more aensitize~ added, the greater the Gc value.

However, the viscosity of the natural rubber latex also increasea rapidly alon with the increase of sensitizers added.

Some sensitizens, such as TMPTA, can decrease the optimum dose from about 200 kGy to approximately 20 kGy ac~~rding to our experiment. The tensile -116th of the film can reach round 20 MPa. Other physical properties are comparable to those of unsensitized.
