    Abstract: Polyurethane polymers are made from a reaction mixture that contains a polyisocyanate, a hydroxylmethyl-containing fatty acid or ester, and another polyol, polyamine or aminoalcohol. The carboxylic acid or ester group on the hydroxymethyl-containing fatty acid or ester are capable of engaging in a variety of reactions with the polyisocyanate and/or amine or hydroxyl groups present in the reaction mixture. This allows for good quality, high molecular weight polymers to be produced even though the hydroxymethyl-containing fatty acid or ester tends to be a low functionality material.

    Abstract: The present invention is a transparent thermoplastic polyurethane (TPU) comprising structural units of: a.) a diisocyanate; b.1) a polyester diol and b.2) a specific polyether diol and c.) a chain extender. The TPU has good combinations of light transmission and clarity, tensile strength, low temperature flexibility, and high moisture vapor transition rates compared to other commercial or known TPUs. A preferred example composition is a TPU that is based on MDI as the diisocyanate monomer, polycaprolactone as a polyester diol, an EO capped EO/PO polyether diol containing less than 20% EO, and butanediol as chain extender. These composition have good combinations of clarity, tensile strength, hydrolytic stability and processability compared to TPUs prepared using either polyester or polyether diols alone or the combination with a higher EO polyether diol.

    Abstract: A process for the recovery of scrap polyurethane polymer in the form of a polyol, and the use of said polyol to prepare a fresh polyurethane polymer. Said process involves thermally treating scrap polyurethane at an elevated temperature with a liquid mixture which consists of an alkanolamine and a metal hydroxide and subsequently reacting the resulting intermediate product with an alkylene oxide comprising propylene oxide to obtain polyol. The recovery process is characterized in that the weight ratio of scrap polyurethane to liquid mixture is from at least 12:1, and the liquid mixture contains the alkanolamine in from about 70 to about 95 weight percent. The recovered polyol can be used to prepare fresh polyurethane foam that exhibits enhanced physical properties at a reduced isocyanate consumption compared to similar foam prepared in the absence of any recovered polyol.

    Abstract: The present invention concerns a thermoplastic polyurethane material which is the reaction product of (1) a mixture of (a) 0.86 to 0.98 mole equivalent of a polyester diol having the molecular weight of from 650 to 5,000 and (b) 0.02 to 0.14 mole equivalent of a polyether diol having the molecular weight of from 2,000 to 5,000, and (2) a difunctional chain extender with (3) an organic diisocyanate. These polyurethane materials exhibit high resistance to severe abrasion forces while retaining desirable mechanical properties and are useful for the manufacture of shoe soles, ski boots, ski bindings, conveyor belts and screens used by mining industry and the like.

    Abstract: A process for preparing a hybrid polyester-polyether polyol comprises contacting a carboxyl group-containing component and an epoxide, optionally in the presence of one or more of a double metal cyanide catalyst, a superacid catalyst, a metal salt of a superacid catalyst and/or a tertiary amine catalyst, under conditions such that a hybrid polyester-polyether polyol is formed. The hybrid polyester-polyether polyol offers the advantages of both ester and ether functionalities when used in a polyurethane formulation, thus enhancing physical properties. The process results in products having narrow polydispersity, a low acid number and unsaturation, and reduced byproduct formation, particularly when the double metal cyanide catalyst is employed.
