Provided herein is a composite material that includes at least one thermoresponsive polymer and at least one organic foam material. Further provided herein is a method for producing the composite material and also to the use of the composite material for cooling and for regulating temperature.

The application relates to a method and apparatus for producing a solid foam continuously. A homogeneous suspension is formed from a raw material in which the suspension comprises a solidifying agent, and a foam mixture which comprises bubbles is formed by mixing air bubbles into the suspension. The foam mixture is injected via at least one nozzle to form a foam pattern and the foam pattern is laid on a moving surface and the foam mixture of the foam pattern is solidified in order to form a solid foam such that the bubbles of the foam mixture shrink in off-length directions to form the shaped bubbles. Further, the application relates to the product and the use of the method.

Provided are a polymer material that contributes to environmental protection, has biodegradability, has excellent well-balanced mechanical properties, self-adhesion, and the like, is flexible, and has a reduced variation in the properties. The present invention provides a biodegradable rubber composition comprising natural rubber and an inorganic substance powder in a mass ratio of 45:55 to 10:90, and modified cellulose in an amount of 0.5 part by mass to 10.0 parts by mass relative to 100 parts by mass of the natural rubber.

This cellulose composition contains: (A) a water-soluble cellulose ether, (B) water-insoluble cellulose particles and (C) water. The cellulose composition serves as a novel biomass material which uses biodegradable cellulose that places little burden on the environment, and exhibits excellent shape retention properties.

A rubber composition containing a rubber and modified cellulose fibers, wherein one or more substituents selected from substituents represented by the following general formulas (1) and (2): —CH.sub.2—CH(OH)—R.sub.1 (1), —CH.sub.2—CH(OH)—CH.sub.2—(OA).sub.n—O—R.sub.1 (2), wherein each R.sub.1 in the general formulas (1) and (2) is independently a linear or branched alkyl group having 3 or more carbon atoms and 30 or less carbon atoms; n in the general formula (2) is a number of 0 or more and 50 or less; and A is a linear or branched, divalent saturated hydrocarbon group having 1 or more carbon atoms and 6 or less carbon atoms are bonded to cellulose fibers via an ether bond, wherein the modified cellulose fibers have a cellulose I crystal structure. The rubber composition of the present invention can be suitably used for machine tool parts, household electric appliance parts, automobile parts, and the like.

The invention discloses an expandable copolymer resin used for manufacturing a lost foam casting model and a preparation method thereof, wherein the molecular weight of the expandable copolymer resin is 150000-300000, and the expandable copolymer resin comprises mixed monomers, deionized water, a cellulose ether dispersant, sodium salt, an initiator, a foaming agent and a molecular weight regulator; the mixed monomers comprise MMA and ST, wherein MMA accounts for 70-95% wt of the mixed monomers, and ST accounts for 5-30% wt of the mixed monomers. The model formed by the expandable copolymer resin has the advantage of reducing or eliminating carbon defects of castings when casting cast iron and cast steel.
