Thermal Optical Analysis of Cholesteryl Methacrylate and Methyl Methacrylate Copolymers [PDF]
As a side chain type of liquid crystalline polymer, the copolymers of cholesteryl methacrylate and butyl methacrylate were synthesized. When the mesomorphic behavior of the copolymers was examined with a polarized microscope, the observed transition temperatures were so much varied that the mesomorphic behavior had to be studied by thermal optical ...

Fluorescently Tagged Poly(methyl methacrylate)s
Plastic pollution is a global problem affecting the environment and, consequently, people’s well-being. Careful and timely end-of-life plastic recycling is certainly a way, albeit a partial one, to remedy the problem.
