Application of solubility parameters in the preparation of PMMA with permanent antistatic, high toughness, and excellent optical properties

Abstract

In this paper, a novel kind of PMMA copolymer, P(MMA‐co‐MAA‐co‐SPMA), with permanently antistatic, high toughness, and high transparent properties, was synthesized via radical copolymerization. Herein, we selected the appropriate compatibilizer α‐methacrylic acid (MAA) and release agent (lauryldiethanolamine) through the calculation of solubility parameters for industrial mass production. What is more, the polymer's molecular weight was increased by improving the polymer's synthesis process. The structure and properties of the obtained copolymer were characterized. With 0.6 wt% of the 3‐sulfopropyl methacrylate potassium salt (SPMA), the copolymer exhibits nearly unchanged transparency with neat PMMA, and its unnotched impact strength reaches 16 kJ/m2. The surface resistance of the copolymer could be reduced to 1010 Ω, which could be considered as antistatic materials. Finally, the antistatic mechanism was analyzed. The main reason is that the hydrophilic group absorbs water to form a conductive layer on the surface, and 3‐sulfopropyl methacrylate potassium salt (SPMA) is an ionic monomer that can form ion channels in water molecules, further accelerating the leakage of accumulated electrostatic charges and improving the antistatic properties of the copolymer. The method of selecting compatibilizers and release agents through solubility parameters provides more opportunities for the development of PMMA with excellent comprehensive performance.

Methyl Methacrylate-Based Copolymers: Recent Developments in the Areas of Transparent and Stretchable Active Matrices

“…The surface of pure plastic PMMA has a tendency to accumulate static charges. Chen et al have developed an antistatic PMMA copolymer with high tensile strength and transparency . A terpolymer of PMMA with methacrylic acid (MAA) and 3-sulfopropyl methacrylate potassium salt was synthesized after selecting the monomers through theoretical simulations.…”

The surface resistance and tensile strength of the terpolymer were higher than pure PMMA.…”

Fabrication of Permanent Antistatic PMMA Copolymer for Enhanced Antistatic and Mechanical Properties

“…In the previous research, we introduced the reactive antistatic agent 3-sulfopropyl methacrylate potassium salt into the PMMA molecular chain by copolymerization, and the surface resistance of PMMA was reduced to 10 9 Ω while ensuring high transmittance . Subsequently, to optimize the antistatic system, the appropriate compatibilizer was selected through the calculation of solubility parameters so that the mechanical properties of PMMA were further improved, but the surface resistance of the material was increased from 10 9 to 10 10 Ω . On this foundation, this chemical modification method was still used in this study.…”

Allyltrimethylammonium chloride (TMA), with the strong antistatic property, was selected as an antistatic agent, and acrylic acid (AA) was selected as a compatibilizer.…”

Preparation and Characterization of PAM‐b‐DOPOAA by ATRP

“…Many polymers need to improve their antistatic ability and flame retardant effect, [1] and often need to add two or more small molecule additives, small molecule additives can play a certain role in a short period of time, but the durability is not good, a long time will be separated from the polymer, and the polymer is not very compatible, small molecule additives will be separated from the polymer, the role played by the corresponding disappearance. In order to improve its durability, [2] In order to improve its durability, this paper chooses polymer auxiliaries with two functions, namely block copolymers with two chain segments. A macromolecule with two modified functional groups, both hydrophilic amide groups, and flame retardant P−H bond, [3] thus achieving a multifunctional agent.…”
