'''पॉलीमेथिल मेथाक्रिलेट''' (Polymethyl methacrylate / PMMA) एक पारदर्शी थर्मोप्लास्टिक है। इसे एक्रेलिक ग्लास (acrylic glass) भी कहते हैं। प्लेक्सिग्लास (Plexiglas), एक्रीलाइट (Acrylite), ल्यूसाइट (Lucite), तथा पर्सपेक्स आदि इसके व्यापारिक नाम हैं। शीट के रूप में इसका उपयोग [[कांच|काँच]] के विकल्प के रूप में होता है। यह काँच से हल्का तथा विशरणरोधी (shatter-resistant) भी है। इसका कास्टिंग रेजिन के रूप में भी प्रयोग किया जा सकता है। इसके अलावा भी इसके अनेकों उपयोग हैं।<br />
