Assignee:

Danisco A/S - Copenhagen

International Classification:

C08G 18/00

US Classification:

521170, 521155, 521174

Abstract:

The invention relates to a foamed isocyanate-based polymer derived from a reaction mixture comprising an isocyanate, an active hydrogen-containing compound, a blowing agent and a highly branched polysaccharide which is derivatized to provide a hydrophobicity which renders it compatible with a polyether polyol with which the underivatized polysaccharide is incompatible. Further the invention relates to a mix and a process for the production of isocyanate-based polymer. The mix for the production of a foamed isocyanate-based polymer comprises a mixture of the derivatized polysaccharide of the invention and an active hydrogen-containing compound. The process for producing a foamed isocyanate-based polymer comprises the steps of: contacting an isocyanate, an active hydrogen-containing compound, a derivatized highly branched polysaccharide and a blowing agent to form a reaction mixture and expanding the reaction mixture to produce the foamed isocyanate-based polymer. The derivatized highly branched polysaccharide of the invention has an active hydrogen functionality of at least 15 and comprises randomly bonded glucopyranose units, having an average number of 10-100 glucose residues.

Abstract:

The invention relates to a highly branched polysaccharide which is derivatized to provide a hydrophobicity which renders it compatible with a polyether polyol with which the underivatized polysaccharide is incompatible. Further the invention relates to a mix for the production of polyurethane. The mix comprises a mixture of the derivatized polysaccharide and a polyether polyol. The polysaccharide of the mix is derivatized to provide a hydrophobicity which renders it compatible with a polyether polyol with which the underivatized polysaccharide is incompatible. The derivatized highly branched polysaccharide used in the invention has an active hydrogen functionality of at least 15 and comprises randomly bonded glucopyranose units, having an average number of 10-100 glucose residues.

International Classification:

C08G 18/06
C07C 265/12

US Classification:

521160, 564248

Abstract:

Disclosed is a method for the production of highly stable, liquid isocyanurate-modified PMDI compositions having relatively higher viscosity and a generally comparable functionality, as compared to conventional PMDI. An admixture of the isocyanurate-modified PMDI with conventional PMDI is suitable for use in the manufacture of a variety of polyurethane products, including rigid and flexible foams, coatings, elastomers and sealants. Foams produced using this admixture exhibit properties that are comparable to foams produced from standard polymeric MDI of comparable viscosity that don't contain isocyanurate moieties.

International Classification:

C08G 1814
C08G 1832
C08G 1872

US Classification:

521164

Abstract:

Isocyanate-reactive compounds are prepared by the reaction of TDI distillation residue with a polyol in such proportions as to obtain a reaction product having an OH-number (mg KOH/g) of about 200 to about 700. The TDI distillation residue is obtained from the distillation of the product of phosgenating toluene diamine to the corresponding toluene diisocyanate and has a toluene diisocyanate content of about 30% to about 70% by weight. The isocyanate-reactive compounds are useful in polyurethane formulations.

US Classification:

528 61

Abstract:

This invention relates to a method of fabricating a thermoplastic elastomer which comprises the steps of: (a) fabricating a polyol having a molecular weight of between about 2,000 and about 20,000 and having a level of end group unsaturation of no greater than 0. 04 milliequivalents per gram of polyol, said polyol being fabricated in the presence of a double metal cyanide catalyst, (b) reacting said polyol with a diisocyanate to produce an isocyanate-terminated prepolymer, and (c) reacting said isocyanate-terminated prepolymer with a difunctional isocyanato-reactive chain extender in a mold or in an extruder in order to produce a soft elastomer characterized by a Shore A hardness of between about 10 and about 70. Also claimed is the elastomer produced by the above method utilizing a one-shot technique.
