[0001] The present invention relates generally to polyurethane and in particular, to polyurethane elastomer compositions, articles of manufacture comprising same, and preparation processes.
RELATED APPLICATIONS
[0002] This application is the Canadian counterpart of U.S. Application Serial No. 17,015,808 filed September 9, 2020 (now U.S. Patent No. 10,934,385 issued and published March 2, 2021).
[0003] In related U.S. Application Serial No. 17//015,669 filed September 9, 2020 (now U.S. Patent No. 10,934,384 issued and published March 2, 2021), there are illustrated biocide containing polyurethane elastomers, foam compositions, and processes thereof.
BACKGROUND
BACKGROUND
[0004] In United States Patent Publication 2012/0258269 Al there is disclosed a process for preparing polyester polyols from at least one carboxylic acid recovered from natural raw materials, and having at least two acid groups, at least one polyhydric alcohol, at least one organic phosphite group, and at least one Lewis acid.
The recited polyol polyester composition according to this publication can be selected to prepare various thermoplastic polyurethane products.
100051 United States Patent 9,458,277 discloses a method for the preparation of polyurethane elastomers based on polyester diols formed from diacids, such as Date Recue/Date Received 2021-11-17 succinic acid, a carbohydrate, diols such as 1,3-propanediol, and an organic diisocyanate.
[0006] Also, in United States Patent Publication 2013/0035448 there is disclosed a method for producing a biomass resource-derived polyurethane by reacting a dicarboxylic acid and an aliphatic diol to produce a polyester polyol and reacting the polyester polyol and a polyisocyanate compound, where the dicarboxylic acid contains at least one component derived from biomass resources, a content of an organic acid in the dicarboxylic acid is more than 0 ppm and not more than 1,000 ppm relative to the dicarboxylic acid, and a pKa value of the organic acid at 25 C. is not more than 3.7.
[0007] Athletic shoes, whether for running or engaging in sports activities, lose massive amounts of energy due to impact and shock, especially in the midsoles.
A
well cushioned shoe disperses the impact and shock that for a period of time keeps the feet comfortable and prevents the feet from hurting. High performance athletic shoes have well cushioned midsoles that transfer the impact into forward motion or lift-offspring-like effect, as if the impact/shock is being turned into a return energy.
[0008] Thus, a number of polyurethane elastomers are known, many of which possess deficiencies such as insufficient life times, poor hardness, degradation, unsuitable and consistent properties like tensile strengths, discoloration, lack of continued suitable flexibilities, complex and costly preparation processes, including the absence of components, such as phosphites, and the absence of polyesters like the disclosed amorphous polyester resins and semi-crystalline polyester resins in combination with other components, and excellent and in embodiments, improved bio-contents.
[0009] There is a need for polyurethane elastomers that can be selected for molded flexible parts, footwear insoles or midsoles, and which elastomers with, for example, a combination of specific mechanical properties, such as a hardness of, for example, from about 20 to about 60 Asker C, from about 15 to about 60 Askar C, from about 20 to about 50 Asker C, and from about 15 to about 35 Askar C, and for Date Recue/Date Received 2021-11-17 insoles a hardness of, for example, from about 22 Asker C to about 44 Asker C, and for midsoles a hardness of from about 40 to about 60 Asker C, and containing, for example, an amorphous polyester or a semi-crystalline polyester with excellent melting points.
[0010] Yet also, there is a need for polyurethane elastomer foams and processes wherein there are selected surfactants, plasticizers, dyes, crosslinkers, chain extenders, plasticizers and blowing, or foaming agents.

[0012] Another need resides in the generation of polyurethane elastomers where there is eliminated a number of semi-crystalline polyester polyols that must be heated above 50 C prior to permitting the initiation of foaming, and which polyols increase preheating time, create a highly viscous liquid difficult to use in manufacturing methods, and where elevated temperatures increase the reaction kinetics and cause less control over the reaction thereby adversely affect product quality.
[0013] Additionally, there is a need for polyurethane elastomer foams where the viscosities of the polyol ester reactant may be decreased with the use of certain plasticizers.
[0014] There is a need for footwear like athletic shoes with superior energy return, that is the ability of footwear, such as athletic shoes to receive and release energy upon impact on striking the ground and resilience, which is the ability to spring back into its original shape (elasticity) after being compressed and measured by the rebound percentage, and where in embodiments the disclosed polyurethane foam-based midsoles have, for example, a return energy of from about 50 percent to about 100 percent, from about 55 to about 75 percent, and from about 55 and from Date Recue/Date Received 2021-11-17 about 70 as measured by VF Corporation with their proprietary equipment, hydrolytic stability, excellent resilience of, for example, from about 25 percent to about 60 percent, from about 30 percent to about 60 percent, from about 25 percent to about 45 percent, and improved compression sets.
[0015] Yet in embodiments, there is a need for polyurethane elastomer foams selected for insoles and midsoles that have excellent mechanical properties, and where the insoles have a density (grams/centimeter3) of, for example, from about 0.2 to about 0.3; a hardness (Asker C) of, for example, from about 15 to about 55;
an elongation of, for example, from about 150 percent to about 700 percent, from about 450 percent to about 650 percent; a tensile strength of, for example, equal to or greater than about 20 MPa; a tear strength of, for example, equal to or greater than about 2 Newtons/millimeters2, a rebound test resilience of, for example, equal to or from about 40 to about 50 percent; a compression set, for example, of equal to or less than about 6 percent; and a hydrolytic stability of, for example, equal to or at least 80 percent; and for midsoles a density in grams/centimeters3 of, for example, equal to or less than 0.5; a hardness (Asker C) of, for example, from about 30 to about 50; an elongation of equal to or greater than about 300 percent; a tensile strength in MPa of, for example, equal to or greater than about 10; a tear strength in Newtons/millimeters of, for example, equal to or greater than about 3; a rebound test resilience of, for example, equal to or greater than about 60; a compression set of, for example, less than or equal to about 20 percent; an abrasion of, for example, less than or equal to about 300 percent; and a hydrolytic stability of, for example, equal to or at least 80 percent.
[0016] Also, therefore there is a need for insoles with a density (grams/centimeters3) of from about 0.2 to about 0.3; a hardness (Asker C) of about 15 to about 35; an excellent elongation of from about 450 to about 650 percent; a tensile strength (MPa) of less than about 20; a tear strength (Newtons/millimeters) of less than about 2; a rebound test resilience of from about 40 to about 45 percent; a compression set of greater than about 6 percent; and a hydrolytic stability of about 80 Date Recue/Date Received 2021-11-17 percent and above; and for midsoles, a density (grams/centimeters3) of greater than about 0.5; a hardness (Asker C) of from about 30 to about 50; an excellent elongation, a tensile strength (MPa) of less than about 10; a tear strength (Newtons/millimeters) of less than about 3; a rebound test resilience of less than about 60 percent; a compression set of less than about 20 percent; an excellent and improved abrasion or hardness of more than about 300 percent; and a hydrolytic stability of about 80 percent and above.
[0017] An important need resides in polyurethane elastomer foams with a bio-content of, for example, from about 50 to about 90, from about 60 to about 90 percent, from about 60 percent to about 75 percent, from about 50 percent to about 90 percent, from about 40 percent to about 85 percent, from about 70 percent to about 85 percent, and from about 60 percent to about 80 percent.
