Methane dichloride

Bisphenol A glycerolate (1 glycerol/phenol) diacrylate (BPA.GDA) (Sigma Aldrich, Steinheim am Albuch, Germany) and ethylene glycol dimethacrylate (EGDMA, ≥97.5%) (Sigma Aldrich, Steinheim am Albuch, Germany) were used as monomers in the polymerization reaction. Moreover, 2,2-dimethoxy-2-phenylaceto-phenone (Irqacure^® 651) was applied (Sigma Aldrich, Steinheim am Albuch, Germany) as the photoinitiator of polymerization. In both systems, methyl methacrylate (MMA, ≥99.0%) (Merck, Darm-stadt, Germany) was employed as an active solvent. The PC (polycarbonate) was pur-chased from Lotte Chemical (Seoul, South Korea), density 1.15–1.25 g/cm³, molecular weight >1.000 g/mol. Methane dichloride (99.8%) (Merck, Darmstadt, Germany) was used as a solvent for commercial PC. Structures of listed reagents are presented in Figure 1. For swelling test, we used the acetone (99.5%) and hydrochloric acid (36.5–38.0%) from Merck. The purified water was provided by Millipore UMCS (Lublin, Poland).

Diphenyl carbonate, methane dichloride, and tetrahydrofuran were purchased from Merck (Merck, Darmstadt, Germany). Catalysts: zinc acetate, 4-(dimethylamino)pyridine (DMAP) and benzyltriethylammonium chloride also were obtained from Merck (Merck, Darmstand, Germany). Purified water was delivered by Millipore (Millipore, UMCS Lublin, Poland).
