They have too large a molecular size to dissolve the polymer at room temperature but they may be incorporated at elevated temperatures to give mixtures stable at room temperature. Most common plasticizers for PVC include alkylphthalates, aryl phosphates, expoxidized oils. Generally, 40-60 parts of plasticizer per 100 parts of polymer are used for most common applications epoxidized vegetable oi O n O C C-(CH 2 ) -C-O-R tritotyl phosphate O O O P diisooctyl phthalates O O-C-O-R R-O-C-...
