Polymer foam bodies are made from phosphorus-containing thermoplastic random copolymers of a dialkyl (meth)acryloyloxyalkyl phosph(on)ate. Foam bodies made from these copolymers exhibit increased limiting oxygen indices and surprisingly have good properties. In certain embodiments, the phosphorus-containing thermoplastic copolymer is blended with one or more other polymers and formed into nanofoams.

A particle-dispersed polyimide precursor solution contains: a polyimide precursor consisting of a polymer of a tetracarboxylic dianhydride and a diamine containing a fluorene-based diamine having a fluorene skeleton; particles; and an aqueous solvent containing water.

Poly(tetramethyl-p-silphenylenesiloxane) (PTMPS) membranes and porous articles made therefrom that have a matrix tensile strength in at least one direction from about 1 MPa to about 50 MPa, a matrix modulus greater than about 100 MPa in at least one direction, a porosity greater than about 30%, and a microstructure of nodes interconnected by fibrils are provided. The PTMPS polymer forming the PTMPS membranes and porous articles has a crystallinity of at least about 70%, a polydispersity from 1 to 5, and a weight average molecular weight from about 350 kDa to about 5 MDa. The PTMPS membranes may be asymmetric, meaning that the observed pore structure on one side of the PTMPS membrane is different than the pore structure on the opposing side of the PTMPS membrane. Methods of forming porous PTMPS articles are provided. Dense PTMPS articles and methods of making the same are also provided.
