The mixture includes, based on the total weight of the mixture, from 50.0 wt % to 99.8 wt % of a polyol component including at least one polyether polyol, from 0.1 wt % to 50.0 wt % of an additive component including at least one catalyst, and from 0.1 wt % to 6.0 wt % of a preformed aqueous polymer dispersion. The preformed aqueous polymer dispersion has a solids content from 10 wt % to 80 wt %, based on the total weight of the preformed aqueous polymer dispersion, and is one of an aqueous acid polymer dispersion or an aqueous acid modified polyolefin polymer dispersion in which the polyolefin is derived from at least one C2 to C20 alpha-olefin.

摘要： There is described a foamed isocyanate-based polymer derived from a reaction mixture comprising: an isocyanate; a polyol composition comprising a first prescribed amount of polymer particles dispersed in a base polyol; a second prescribed amount of biomass-based carbonaceous particulate material; and a blowing agent. In one embodiment, the foamed isocyanate-based polymer having an Indentation Force Deflection when measured pursuant to ASTM D3574-11 which is within about 15% as that of a reference foam produced by omitting the biomass-based carbonaceous particulate material from the reaction mixture and increasing the amount of polymer particles in the polymer polyol composition to equal the sum of the first prescribed amount and the second prescribed amount. In another embodiment, the foamed polymer has a cellular matrix comprising a plurality of interconnected struts, the biomass-based carbonaceous particulate material conferring to the cellular matrix a load efficiency of at least about 5 Newtons/weight % of biomass-based carbonaceous particulate material. A process to produce the foamed isocyanate-based polymer is also described. A polyol-based dispersion to produce the foamed isocyanate-based polymer is also described. It has been discovered that a relatively expensive petroleum-based copolymer polyol can be fully substituted by a relative inexpensive bio-based (amorphous carbon) dispersion with no significant compromise in important physical properties in the resulting polyurethane foam.

摘要： The present invention relates to a method of synthesis and the use of foamed, cross-linked polyurethane polymers, as a three-dimensional support called a “scaffold” for cell cultures in vitro and for in vivo implantation for the regeneration of connective tissues such as adipose tissue, osteochondral tissue and bone tissue. In particular, the invention relates to a method of preparing polymers or foamed polyurethane co polymers, having improved hydrophilia, which involves the use of two types of catalyst, one for the cross-linking reaction and one for the foaming reaction and the use of at least one polar aprotic high-boiling solvent. Said method comprises the following steps in sequence: a) providing a solution of a polyol or a mixture of polyols in a solvent or mixture of solvents; b) heating the solution in step a) to a temperature higher than the softening temperature of the polymer precursors; c) optionally adding an organic or inorganic filler material; d) adding to the mixture in step c) an aliphatic poly-isocyanate or a mixture of poly-aliphatic isocyanates; e) adding to the mixture in step (d)) a porogenic additive; f) adding to the mixture in step e) simultaneously a cross-linking catalyst of polyols with poly-isocyanates and a foaming catalyst to form a foamed polyurethane polymer or co-polymer; g) isolating the foamed polyurethane polymer or co-polymer produced in step f).
