Water sorption (WS) of BTHM and ETHM copolymers and their ACP and OX50/ZrO2 glass composites. Indicated values represent mean values for five specimens in each group. SDs (in mass fraction %) were: ≤ 0.45 for BTHM copolymer, ≤ 0.77 for BTHM ACP composites, ≤ 0.62 for BTHM OX50/ZrO2 glass composites, ≤ 0.57 for ETHM copolymer, ≤ 0.48 for ETHM ACP composites and ≤ 0.44 for ETHM OX50/ZrO2 glass composites.
