抄録

Agricultural PVC film containing PVC 64.5%, DOP (dioctylphthalate) 32% as a plasticizer, Ca-Zn stearates and surface active agent was treated in 0-7 M NaOH solutions at 150-250°C for 0-12h, in order to study the behavior of degradation and characteristics of produced char.<BR>The degree of weight loss due to the decomposition reached 31% for the reaction in 3 M NaOH over 225°C for Oh, which corresponded to the loss of all the plasticizer contained in the agricultural PVC film. Under the same conditions, DOP was hydrolyzed quantitatively to phthalic acid and isooctyl alcohol by the alkali catalyst. In the hydrothermal reaction, the pores in size 10-12, em were produced in the film by the hydrolysis of DOP, besides the succeeding parallel dehydrochlorination of PVC produced smaller pores and brought about the shrinkage of film. The pore size became smaller, about 1-8μm for 12h, along with time.
