SULFOBETAINE-MODIFIED POLYURETHANE OR POLYUREA FOAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17754838 titled 'SULFOBETAINE-MODIFIED POLYURETHANE OR POLYUREA FOAM

Simplified Explanation

The hydrophilic foam described in the patent application is made from a polymer formed from a betaine prepolymer, which is a reaction product of a betaine compound and a polyfunctional isocyanate compound. The betaine compound has a specific formula, while the isocyanate compound has a different formula.

• The polymer in the hydrophilic foam is derived from a betaine prepolymer.
• The betaine prepolymer is formed by reacting a betaine compound with one or more polyether glycols and a polyfunctional isocyanate compound.
• The betaine compound has a specific formula with hydrocarbon groups and an anionic functional group.
• The isocyanate compound has a specific formula with aliphatic or carbocyclic groups.

Potential Applications

The hydrophilic foam could be used in medical dressings, wound care products, or as a component in personal care products.

Problems Solved

This technology provides a way to create a hydrophilic foam with specific properties, such as absorbency and softness, which can be beneficial in various applications.
