Interpenetrating polymer networks (IPN's), composed of polyisoprene (PI) and polyurethane (PU), together with a process for their preparation and their use in the manufacture of medical devices, such as catheters and catheter balloons, are disclosed. Both components are elastomers. The PI component is chemically crosslinked. The PU component is crystallizable and contains only physical crosslinks. The IPN's have glass transition temperatures in the range of from -65.degree. C. to -40.degree. C.

This invention relates to acrylic polymers and more specifically to polyalamides and polyacrylates such as poly{2-[(N-2-methyl-5-nitrophenylamino)ethyl acrylate]} and poly[(N-2-methyl-4-nitrophenyl)acrylamide]. These acrylic polymers are particularly useful as nonlinear optical components in various electrical devices for processing optical amplifiers, generators, computational devices and the like.
