Poly(methyl methacrylate) (PMMA) has been exploited as a material for over 60 years. More commonly recognized under trade names such as Lucite, Perspex or Plexiglas, it was originally developed during the 1930s as a safe replacement for glass in aircraft canopies. PMMA has the important advantages of being lighter and less brittle than glass; it is more easily fabricated and is much less likely to cause cuts and lacerations when broken. Nowadays, these advantages and others are exploited in applications ranging from hospital incubators to automotive rear light clusters. The development of means to toughen and increase the glass transition temperature (Tg) of PMMA has further enhanced its utility.

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
Occasionally, collections of JCE back issues become available for donation to individual teachers, schools, or libraries. JCE matches collections with interested recipients. Recipients pay shipping costs or pick up the collection.
