Disclosed are elastomer compositions. The elastomer compositions include at least 20% by weight, based on the total weight of the elastomer composition, of a polymer matrix; and (b) 0.1 to 70% by weight, based on the total weight of the elastomer composition, of a solid isocyanate residue of isocyanate manufacturing, the solid having, prior to its inclusion in the elastomer composition, a Dparticle size of no more than 70 microns. Elastomer products made using these elastomer compositions can include, for example, a tire treadstock, a tire sidewall stock, a roofing membrane, a door seal, a window seal, a trunk seal, a hood seal, a hose, such as a hose in a vehicular cooling system circuit, or a hanger element attaching an exhaust system to a vehicle underfloor.

Elastomeric compositions containing a solid residue of isocyanate manufacturing

Disclosed are ethylenically unsaturated macromers produced using a residue of an isocyanate manufacturing process. Also disclosed are preformed stabilizers produced using such macromers, polymer polyols produced using such preformed stabilizers, foam-forming compositions produced using such polymer polyols, and foam produced using such compositions.

In one or more embodiments, the present invention provides a novel approach to the addition of plasticizers for softening TPUs, i.e., lowering the durometer and the melt viscosity. This approach involves incorporating bonded sulfonate groups with quaternary ammonium counterions into the TPU. In one or more embodiments of the present invention, the softening of TPU is achieved by incorporating an ionic diol, such as N,N-bis (2-hydroxyethyl)-2-aminoethane-sulfonic acid (BES), coupled with various bulky alkyl ammonium cations, during the chain extension step of the TPU synthesis. It is believed that that steric hindrance of the bulky quaternary ammonium groups weakens the dipole-dipole interactions of the sulfonate groups and/or lowers the crystallinity of the hard block, thereby creating additional free volume that softens the polymer and lowers the melt viscosity.

This approach involves incorporating bonded sulfonate groups with quaternary ammonium counterions into the TPU. In one or more embodiments of the present invention, the softening of TPU is achieved by incorporating an ionic diol, such as N,N-bis (2-hydoxyethyl)-2-aminoethane-sulfonic acid (BES), coupled with various bulky alkyl ammonium cations, during the chain extension step of the TPU synthesis. It is believed that that steric hindrance of the bulky quaternary ammonium groups weakens the dipole-dipole interactions of the sulfonate groups and/or lowers the crystallinity of the hard block, thereby creating additional free volume that softens the polymer and lowers the melt viscosity.

The present invention provides a process for producing a rigid polyisocyanurate foam involving reacting at an isocyanate index of from about 175 to about 400, a polyisocyanate with at least one natural-oil polyol containing at least about 35 wt. %, based on the weight of the polyol, of natural oil, having a hydroxyl number from about 175 to about 375 and a hydroxyl functionality of about 2.0 to about 2.8, in the presence of a blowing agent and optionally, in the presence of one or more of surfactants, flame retardants, pigments, catalysts and fillers, wherein the resulting foam has a renewable biobased content of at least 8% by weight. The foams provided by the inventive process possess properties similar to foams produced from petroleum-derived materials and may find use in wall or roof insulation systems. The high biobased content (&#x3e;8%) may allow wall or roof insulation systems containing these foams to be considered for the U.S. Government's preferred procurement program.

Process for preparing rigid polyisocyanurate foams using natural-oil polyols

This invention relates to a novel process for preparing an aliphatic hybrid ester/ether polyol. This process simultaneously transesterifies and alkoxylates a mixture of at least one ester group containing compound which is free of ether groups, and at least one or more hydroxyl group containing compound which is free of ester groups; with the proviso that the mixture has an overall hydroxyl number of less than or equal to 350; with at least one alkylene oxide; in the presence of a mixture of catalysts. The catalyst mixture comprises at least one DMC catalyst, and at least one non-alkaline transesterification catalyst.

DMC catalyzed alkoxylation of esters

The present invention provides a process for the preparation of polyols based on fatty acid esters and starter compounds having Zerewitinoff-active hydrogen atoms and the use thereof for the preparation of polyurethane materials.

Process for the preparation of polyether-ester polyols

The present invention provides flexible conventional polyurethane foams made from at least one polyisocyanate and at least one vegetable oil alkoxylated in the presence of a double metal cyanide (DMC) catalyst, optionally at least one non-vegetable oil-based polyol, generally in the presence of a blowing agent and optionally in the presence of a surfactant, pigment, flame retardant, catalyst or filler. The alkoxylated natural oil must have (a) an ethylene oxide content in the alkoxylated segment greater than 20% by weight, (b) a primary hydroxyl group content of at least 10%, with the sum of (a)+(b) being at least 30% but no greater than 60%, The alkoxylated natural oils are environmentally-friendly, bio-based polyols which can be used to increase the 'green' content of polyurethane foams without having detrimental effects on foam properties.

Flexible polyurethane foams made from alkoxylated natural oil

This invention relates to novel polyether polyols which are prepared by alkoxylation of renewable resource materials, and particularly cashew nutshell liquid (CNSL), and to a process for the preparation of these novel polyether polyols. This invention also relates to flexible polyurethane foams prepared from these long chain polyether polyols, and to a process for the production of these flexible polyurethane foams.

The present invention provides a process for the double metal cyanide (DMC)-catalyzed production of low unsaturation polyethers from boron-containing starters. The polyethers produced by the inventive process may be reacted with one or more isocyanates to provide polyurethane products including coatings, adhesives, sealants, elastomers, foams and the like. The inventive process may be used to prepare fuel additives from C-Cboron-containing polyethers, more particularly from Calcohols.
