Definitions
- the present invention relates, in general to polymers, and more specifically, to polymers made with neutralized polyols, uretdiones and tertiary amine catalysts.
- the resulting allophanate polymers may be used to make coatings, adhesives, castings, composites, and sealants.
- Polyurethane-forming compositions are widely used in a variety of commercial, industrial and household applications, such as in automotive clear-coat and seat cushion applications.
- Polyurethane systems that employ isocyanates which are pre-reacted with
- Uretdiones are a type of blocked isocyanate. Uretdiones are typically prepared by dimerizing an isocyanate to form uretdione(s) with unreacted isocyanate end-groups which can then be extended with a polyol to form a polymeric material containing two or more uretdione groups in the polymer chain.
- uretdiones are referred to as“1 ,3-diaza-2,4-cyclobutanones”, ⁇ ,3-diazatidin-2,4-diones”, “2,4-dioxo-1 ,3-diazetidines”,“urethdiones” or“uretidiones”.
- the polymer has few, if any, free isocyanate groups, which is achieved by controlling the stoichiometry of the polyisocyanate, polyol and by the use of a blocking agent.
- the present invention attempts to alleviate problems inherent in the art by providing such an alternative cross-linking approach to obtain compositions having physical properties similar to those of polyurethane compositions.
- various embodiments of the inventive approach involve crosslinking polyuretdione resins with neutralized polyols in the presence of a tertiary amine catalyst.
- the polyol may be neutralized by reaction with an acid scavenger at a temperature ranging from room temperature (21 ⁇ -24 ⁇ ) to 120 ⁇ .
- the resulting allophanate polymer may be used to make coatings, adhesives, castings, composites, and sealants.
- any numerical range recited in this specification is intended to include all sub-ranges of the same numerical precision subsumed within the recited range.
- a range of "1 .0 to 10.0" is intended to include all sub-ranges between (and including) the recited minimum value of 1 .0 and the recited maximum value of 10.0, that is, having a minimum value equal to or greater than 1 .0 and a maximum value equal to or less than 10.0, such as, for example, 2.4 to 7.6.
- Any maximum numerical limitation recited in this specification is intended to include all lower numerical limitations subsumed therein and any minimum numerical limitation recited in this specification is intended to include all higher numerical limitations subsumed therein.
- compositions and methods are described in terms of “comprising” various components or steps, the compositions and methods can also“consist essentially of” or“consist of” the various components or steps.
- the present invention provides a reaction mixture comprising a polyuretdione resin; a neutralized polyol and a tertiary amine catalyst; and optionally, an additive package (e.g. flow control, wetting agent) and solvent.
- the present invention further provides a method of making an allophanate polymer comprising reacting a polyuretdione resin with a neutralized polyol in the presence of a tertiary amine catalyst, wherein the reaction mixture optionally includes an additive package (e.g., flow control, wetting agent) and solvent.
- the polyol may be neutralized by reaction with an acid scavenger at a temperature ranging from room temperature (21 ⁇ -24 ⁇ ) to 120 ⁇ .
- an acid scavenger at a temperature ranging from room temperature (21 ⁇ -24 ⁇ ) to 120 ⁇ .
- the present invention provides a m ethod for producing an allophanate polymer by the following route: Tertiary Amine
- the inventive allophanate polymer system is particularly applicable in the production of coatings, adhesives, castings, composites, and sealants.
- polymer encompasses prepolymers, oligomers and both homopolymers and copolymers; the prefix “poly” in this context referring to two or more.
- molecular weight when used in reference to a polymer, refers to the number average molecular weight, unless otherwise specified.
- polyol refers to compounds comprising at least two free hydroxy groups. Polyols include polymers comprising pendant and terminal hydroxy groups.
- coating composition refers to a mixture of chemical components that will cure and form a coating when applied to a substrate.
- adhesive or “adhesive compound” refer to any substance that can adhere or bond two items together. Implicit in the definition of an "adhesive composition” or “adhesive formulation” is the concept that the composition or formulation is a combination or mixture of more than one species, component or compound, which can include adhesive monomers, oligomers, and polymers along with other materials.
- A“sealant composition” refers to a composition which may be applied to one or more surfaces to form a protective barrier, for example, to prevent ingress or egress of solid, liquid or gaseous material or alternatively to allow selective permeability through the barrier to gas and liquid. In particular, it may provide a seal between surfaces.
- A“casting composition” refers to a mixture of liquid chemical components which is usually poured into a mold containing a hollow cavity of the desired shape, and then allowed to solidify.
