Method for improving fracture toughness of polyisocyanurate comprising reaction products

A curable composition for making polyisocyanurate comprising products obtained by combining and mixing at an isocyanate index of at least 100 at least a polyisocyanate composition, a polytetrahydrofuran polyol (P-THF) having average molecular weight in range 1000-5000 g/mol as toughening agent and diols having an average molecular weight &#x3c;1000 g/mol.

Nano-sized polyurea particles or a dispersion of polyurea particles suitable for improving the mechanical properties of a polyurethane material, said particles having at least equivalent diameter dimensions in the nanosize range of 50 nm up to 700 nm, a uniform equivalent diameter particle size distribution, an amount of urethane bonds calculated on the total amount of urea+urethane bonds in said particles of &#x3c;1%, and a glass transition temperature (Tg) of &#x3e;100&#xb0; C., preferably Tg&#x3e;120&#xb0; C., more preferably &#x3e;150&#xb0; C. measured in a second heating cycle after heating to &#x3e;220&#xb0; C. at 20&#xb0; per minute using Differential Scanning calorimetry.

Use of polyurea nanoparticles as performance modifiers in polyurethane materials

A method for providing urea particles in a solvent medium, said method comprising at least the steps of:

Process for making polyurea particles

The invention provides a cross-linkable elestomeric thermoplastic polyurethane that is urea free, isocyanutrate free, oxazolinyl free, functional radically-polymerizable pendant group free and having terminal functional radically-polymerizable groups at both ends, and thermoset polyurethanes obtained therefrom. The invention also provides applications of the compositions, and processes for manufacturing these compositions.
