Abstract
The article describes the effect of incorporating low mol fractions of N-o-tolylmaleimide (MO)/N-p-tolylmaleimide (MP) in poly(methyl methacrylate) (PMMA) on T g , thermal behavior, mechanical, and optical properties. The glass transition temperature (T g ) of PMMA increased by 10-12°C upon incorporation of an ∼ 0.026 mol fraction of N-arylmaleimides. A further increase of N-arylmaleimide content up to 0.1 mol fraction in the copolymers resulted in a further ∼ 10°C increase in T g . The tensile strength and % elongation decreased, whereas modulus increased with increasing maleimide content. The solar transmittance and % transmittance at higher wavelengths of the copolymer sheets having a low mol fraction of N-arylmaleimides (i.e., 0.026-0.05) were comparable to PMMA. © 1995 John Wiley & Sons, Inc.
