Abstract
The antiplasticizing effect of ester derivatives of bisphenol A: 1,1‐bis(4‐hydroxyphenyl)‐2,2‐propane diacetate (DAPP), 1,1‐bis(4‐hydroxy‐3,5‐dichlorophenyl)‐2,2‐propane diacetate (DACPP), 1,1‐bis(4‐hydroxy‐3,5‐dibromophenyl)‐2,2‐propane diacetate (DABPP), 1,1‐bis(4‐hydroxy‐3,5‐dichlorophenyl)‐2,2‐propane dibenzoate (DBCPP), 1,1‐bis(4‐hydroxy‐3,5‐dichlorophenyl)‐2,2‐propane di‐2,4‐dichlorobenzoate (DCBCPP) on polycarbonate was investigated. Obtained results indicate that antiplasticizing abilities of these compounds depend on the number of polar groups in the molecule, as well as on the possibility of tight filling the free volume by the molecules in polymer–antiplasticizer system.
