Copolymers of higher alkyl methacrylates with triallyl cyanurate

Copolymers of higher methacrylates (propyl, pentyl, hexyl, cyclohexyl, heptyl, octyl, and dodecyl) with triallyl cyanurate were synthesized by free-radical polymerization using benzoyl peroxide as initiator. The properties of the copolymers such as thermal stability, T_g, Vicat softening temperature, hardness, refractive indices n_D, chemical stability, density, and shrinkage on polymerization were studied. The influence of the alcohol alkyl chain length in methacrylates and the content triallyl cyanurate in copolymers on their properties is discussed. © 1995 John Wiley & Sons, Inc.
