| abstract | Copolymers of maleic acid semi-esters and at least one other copolymerisable monomer, alone or in mixture with other polymers, expansion agents, fire-retarding agents, fillers, metallic oxides, hydroxides, or carbonates, volatile solvents or non-solvents, are heated at 80 degrees to 350 degrees C at which temp. by decomposition and/or vaporisation, at least one of the components produces an evolution of gas. A preferred compn. consists of (a) 80-99.5% of a copolymer of maleic semi-ester, styrene and isobutylene, (b) 0.5 to 20% of a solvent or blowing agent, and (c) 0 to 10% of metal oxide, hydroide or carbonate. The cellular material formed are white and of density 0.1 to 0.9 g/cm3 and have good heat resistance. They are used for packaging. |
