摘要

A conversion rate of more than 90% was obtained in sensitized polymerization

and the output of radiation was double at a reduced total dose of 0.5 Mrad as compared

original 1 Mrad.

The unpolymerized monomer could be removed simply by extraction under reduced pressure to save a large volume of organic solvent. The quota of raw material consumption would be reduced without influencing quality of the product.

experiments indicated that the content of water in trioxane

even up to 300 ppm

has no effect on conversion о molecular weight. Irradiated trioxane was stored in dry air kept away from light at room temperature could effectively sustain the lifetime of active species even after a lapse of one month.

The infrared spectrum

molecular weight distribution and physical mechanical properties of the product from sensitized radiation polymerization were identical with those of the unsensitized process.
