Analysis of Methyl Methacrylate in Polymethyl Methacrylate Plastics by GC

Introduction

Due to the high level of concern for food safety, attention is being focused on residual organic solvents in food packaging. Utensils and food packaging materials are subject to standards controlled through material testing as specified in Japan's "Food Sanitation Act-Specifications and Standards for Food, Food Additives, Etc., Chapter III Apparatus and Containers and Packaging." Polymethyl methacrylate is primarily used in table articles such as chopsticks, cups, soy sauce dispensers, etc. A separate food packaging standard is provided for the monomer methyl methacrylate. Here we introduce an example of analysis of methyl methacrylate in plastics in which polymethyl methacrylate is the main ingredient.
