PMMA-based copolymers demonstrate outstanding mechanical and optical properties owing to high transparency, lightweight nature, high impact resistance, and stress relaxation across glass transition temperature.

Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic, used as an engineering plastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others .

2021年1月15日 · Here, a poly(methyl methacrylate-co-ethylene glycol methacrylate-co-sulfobetaine methacrylate) (PMMA-r-PEGMA-r-PSBMA) copolymer is introduced to form zwitterionic poly(vinylidene fluoride) (PVDF) membranes. The MMA segments are used to form hydrophobic interactions with PVDF, while PEGMA units and SBMA units are employed as solubility-enhancing ...

Four series of PMMA-based random copolymers (PMSAm–PMI, PMSAm–CHMI, PMSAm–ATMS, and PMSAm–TF) were synthesized by conventional thermal radical polymerization.

2022年11月20日 · Polymethyl methacrylate (PMMA) is a widely used optical polymer due to its excellent transparency and durability. However, the sole methyl group shows pure PMMA low refractive index and low UV absorbility, and poor thermal stability.

2015年7月29日 · In this study, we developed a novel acrylic material exhibiting heat resistance and low moisture absorption using a bulk copolymerization synthesis process and combing bulky acrylate with methyl methacrylate (MMA) monomers.

2022年5月5日 · In this study we used free radical copolymerization of methyl methacrylate (MMA) and N -hydroxyphenylmaleimide (HPMI) to synthesize various poly (methyl methacrylate– co – N -hydroxyphenylmaleimide) (PMMA- co -PHPMI) random copolymers possessing high glass transition temperatures (Tg).

2019年8月27日 · In this contribution, copolymerization strategy was reported to prepare polymethyl methacrylate (PMMA)-based ultraviolet (UV) shielding copolymers where polymerizable UV absorbers were synthesized and further copolymerized with methyl methacrylate. The copolymer was characterized by 1H …

2023年5月11日 · PMMA（聚甲基丙烯酸甲酯）和Copolymer（共聚物，如MMA或者MMA和MA的共聚物）是最常的电子束光刻胶之一。 也是第一款被发现可用于电子束光刻的聚合物。 他是一种标准的正性电子束光刻胶，具有高分辨率（<10nm）和高对比度，灵敏度较低的特点（约为100uc/cm2 @20kV）。

2022年10月13日 · PMMA-based copolymers demonstrate outstanding mechanical and optical properties owing to high transparency, lightweight nature, high impact resistance, and stress relaxation across glass transition temperature.
