space manufactuof acrylic vs. glass?

Large aquaria are made of acrylic, rather than glass. Acrylic windows can hold tremendous pressure, and (I believe) are more resistant to breakage from impact too.

Has anyone looked at the possibility of manufacturing acrylic in space, for use instead of glass for windows that must contain pressure? What are the advantages and disadvantages as compared to glass?

Seems like most all of the peer-reviewed space habitat designs have assumed use of glass. I strongly suspect this is because when we're talking about needing something by the square mile, we'd darn well better be talking about the cheapest substance with the simplest materials processing which can do the job. One reason why I suspect that even if habitats similar to what Marshall Savage proposes ever get built, they'll be made from steel I-beamsand glass panels, rather than the cable-reinforced silicone plastic Savage recommends.
