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?

Thank you,
