Poly(methyl methacrylate) (PMMA) has found a lot of practical uses, however, how to efficiently and costeffectivelyimprove its relatively low thermal properties remains as an intractable academic challenge. This article reports anovel strategy for improving heat-resistance of PMMA by using biomass syringaldehyde. Syringaldehyde methacrylate(SMA) was first synthesized and then used as comonomer to copolymerize with methyl methacrylate (MMA) through bulkpolymerization and solution polymerization. The copolymers can be obtained in high yield and demonstrate remarkablyimproved heat-resistance according to differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA) andderivative thermogravimetry analyses (DTG). Moreover, the modified PMMA still maintains good light transmittance invisible range. The study provides a new alternative for modifying PMMA, and the modified PMMA may find newapplications as heat-resistant polymeric material which cannot routinely achieved by PMMA itself. In addition, SMA as anew type of green heat-resistant modifier derived from renewable biomass syringaldehyde may have potential applications inheat-resistant modification of materials.
