Abstract

PMMA/MCM-41 (with template), PMMA/SBA-15 (with template), PMMA/SiO₂ composites were prepared by in situ polymerization. The effect of mesoporous molecular sieves MCM-41, SBA-15 and SiO₂on the mechanical properties and the thermal stability of PMMA composite were investigated. The thermal stability of PMMA/MCM-41 (with template) and PMMA/SBA-15 (with template) were greatly enhanced as compared with PMMA. The impact properties of PMMA/SBA-15 (with template) composite were improved by 68.2% compared with PMMA at the 1.2% low filler loading. The CTAB and P₁₂₃ template in the mesopores or on the outer surface of the particle could provide physical entanglement with PMMA matrix to increase miscible. Because the P₁₂₃ (EO₂₀PO₇₀EO₂₀) surfactant had larger PO/EO ratio, which possessed relatively higher hydrophobicity than the low molecular weight CTAB, PMMA/SBA-15 (with template) composite showed better properties than PMMA/MCM-41 (with template) composite.

Key words: PMMA, MCM-41, SBA-15, SiO₂
