摘要

<正> The degradation mechanism of photocrosslinking products formed by cyclized polyisoprene-diazide system under the influence of the different alkyl benzene sulfonic acids was studied. The effects of alkyl chain length and the concentration of alkyl benzene sulfonic acids on the rate of degradation reaction were discussed. It was found that in the initial stage of degradation

the cyclicity ratio and the average fused ring number did not change considerably

but the percentage of uncyclized parts content varied significantly. The suitable mechanism was supposed.
