These organic foams are characterized by relatively large particle and pore sizes, high porosity, and high surface area. Low density open cell carbon foams derived from such organic foams are also shown, as are methods for preparing same.

Abstract: The present invention aims to improve soundproof and heat insulating properties of a foamed plastic by reducing internal cells pressure inside foamed resins. A base polymer such as a polyester-based polyol and a volatile foaming agent having an conjugate unsaturated group (i.e., conjugate double carbon bonds and/or triple carbon bonds) such as chloroprene (bp. 51.degree. C.) and calcium stearate were blended and then mixed with a hardening agent such as hexamethylene diisocyanate. The volatile foaming agent existing in open cells of the foamed plastic sealed in the Al laminated film and between the film and the foamed plastic, i.e., gap, possesses an unsaturated group, such as isoprene. Thus polymerization may occur by irradiating with electron rays, and the inside of the foams and the gap region may be reduced in pressure while the bag of the laminated film retains its shape.
