Hi everyone,
I am curious to know whether polymethyl methacrylate (PMMA) acrylic is ansiotrophic or isotrophic?
My understanding is that when the properties of a material vary with different crystallographic orientations, it is ansiotrophic and when properties of a material is the same in all directions, it is isotrophic.
Hence, PMMA consists of a network of polymer chains and depending on the processing method, is not uniformly distributed, so it is ansiotrophic?
Am I correct in my way of thinking here?
Thanks for any input and ideas
