摘要： Medical articles formed from a polyurethane-based resin including an ionically-charged modifier provide enhanced properties. The polyurethane-based resin is a reaction product of ingredients comprising: a diisocyanate; a diol chain extender; a polyglycol; and an ionically-charged modifier incorporated into a backbone, as a side chain, or both of the polyurethane-based resin. Embodiments include the ionically-charged modifier is a combination of anionic and cationic modifiers. Embodiments include the ionically-charged modifier is zwitterionic. Medical articles herein either have inherent antimicrobial and/or anti-fouling characteristics or can easily bond ionic active agents to provide desirable material properties, including antimicrobial, anti-fouling, and/or radiopacity.

摘要： Disclosed are polyol compositions with a low viscosity that exhibit superior heat resistance, enhanced stability in the presence of water, improved strength, hardness, and molding characteristics relative to known polyurethane materials. Disclosed is a polyol composition comprising: (a) at least one monomeric polyol comprising three or more hydroxyl groups; (b) at least one higher polyol comprising three or more hydroxyl groups; and (c) at least one polyhydroxylated aromatic compound; wherein the at least one higher polyol comprises residues of either or both of the at least one monomeric polyol and the polyhydroxylated aromatic compound linked by one or more carbonate groups, oxygen ether groups, or a combination thereof. Disclosed are methods of preparing the disclosed compositions. Disclosed are articles prepared from the disclosed compositions that exhibit flexural strengths in excess of 10,000 psi and flexural moduli in excess of 400,000 psi, and exhibit outstanding green strength.

摘要： Disclosed is a two-component, liquid curable polyurethane adhesive system comprising an isocyanate reactive part A and an isocyanate functional part B. Either or both parts include substantial amounts of sustainable materials. The inventive mixed adhesive compositions are able to effectively bond to a separation membrane of a filtration apparatus. The invention is also directed to a method of bonding filter assembly components using this two-component curable polyurethane adhesive composition and a filter assembly bonded together using this adhesive composition.

摘要： A polyalkyleneoxy polyol (P) has an average nominal functionality in the range of 2 to 8; a hydroxy number in the range of 10 to 500 mg KOH/g measured according to ASTM method D4272; and a weight average molecular weight in the range of 500 to 25,000 measured using GPC with polystyrene standard and tetrahydrofuran as solvent. The polyol (P) contains ethyleneoxy in an amount in the range of 50 to 95 wt. %, based on the overall weight of the polyol (P).
