Abstract: The invention pertains to a process for manufacturing a glycerol-tricarboxylic acid polyester foam which comprises the steps of combining glycerol and a tri-carboxylic acid to provide a liquid reaction mixture and contacting the reaction mixture with a substrate under polymerization conditions, wherein the substrate has a top layer comprising one or more of metal, metal oxide, and metal halide. The invention also pertains to a glycerol-tricarboxylic polyester foam, in particular a glycerol-citric acid polyester foam, which has a closed cell foam structure wherein at least 90 vol. % of the foam, preferably at least 95% of the foam, is built up from cells having a diameter below 2 mm. The foamed polyester of the present invention is “green”, biodegradable, and non-toxic, and can be cleanly combusted. It finds application in, int. al., packaging materials, insulation materials, and materials with a short life cycle.

Abstract: A composite material comprising 10-98 wt. % of a bio-based particulate or fibrous filler and at least 2 wt. % of a polyester derived from an aliphatic polyalcohol with 2-15 carbon atoms and a polyacid, wherein the polyacid comprises at least 10 wt. % of tricarboxylic acid. Preferably, the filler is in the form of particles, fibers, and/or random or non-random layers. A plant-based filler may be used, in particular a cellulosic or lignocellulosic material, more in particular one or more materials selected from wood chips, wood flakes, sawdust, pulp, e.g., pulp of (recycled) paper or other fiber pulp, and plant-derived fibers such as cotton, linen, flax, and hemp. An animal-derived filler, in particular an animal-derived fiber such as wool, hair, silk, or feathers may also be used. Preferably the polyalcohol is selected from one or more of glycerol, sorbitol, xylitol, mannitol, 1,2-propane diol, 1,3-propane diol, and 1,2-ethane diol, in particular glycerol.
