    摘要： A two stage alkoxlyation process for preparing a short-chain polyether polyol from a starter compound comprising from 3 to 9 hydroxyl groups and at least one alkylene oxide, wherein said starter compound has a hydroxy equivalent weight of from 22 to 90 Da. Said process comprises a first stage alkoxlyation using a superacid catalyst to prepare an oligomeric alkoxylated starter compound that is further alkoxylated to the short-chain polyether polyol of the invention in a second stage using a DMC catalyst. The process of the present invention may be performed continuously, in a batch, or semi-batch process.

    摘要： 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.

    摘要： 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.

    摘要： 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.
