Type I. The soft segment consists only of polyether chains (of one kind) connected at each end to a hard-segment triad consisting of diisocyanate-diamine-diisocyanate, where the diisocyanate is either toluene diisocyanate (TDI) or isophorone diisocyanate (IPDI). [Pg.103]

Isophorone diisocyanate (IPDI) has traditionally been manufactured from isophorone diamine (IPDA) by the conventional phosgenation route as shown below ... [Pg.57]

Daicel Chemical Industries, Ltd., has patented a process for reacting diamines, such as isophorone diamine (IPDA), with dimethyl carbonate. The condensation is accomplished in the presence of an alkaline catalyst, such as methanolic sodium methylate at 70 °C, to produce the diurethane. Treatment of the diurethane with hydrogenated terphenyl containing manganese acetate at 230 °C in vacuo produces isophorone diisocyanate by thermal decomposition. This non-phosgene process has a reported product yield of 93% of IPDI containing 1% isophorone monoisocyanate. [Pg.58]

For environmental reasons there has been interest in methods for manufacturing isocyanates without the use of phosgene. One approach has been to produee diurethanes from diamines and then to thermal eleave the diurethanes into diisocyanates and alcohols. Although this method has been used for the production of aliphatic diisocyanates such as hexamethylene diisocyanate and isophorone diisocyanate, for economic reasons it has not been adopted for the major aromatic isocyanates MDI and TDI.

Brandt [5] prepared a nontacky spray on bandage— patch in a bottle — consisting of the reaction product of isophorone diisocyanate, polydimethyl-siloxane diamine having a Mj, of 5400 daltons, and polypropylene oxide diamine having a Mj, of 2000 daltons. [Pg.27]

For the formation of polyurethane (PU) or polyurea (PUR) shells in miniemulsion systems, usually the diol- or diamine component is water soluble, while the diisocyanate is hydrophobic and thus soluble in organic media. For direct miniemulsions, mostly isophorone diisocyanate (IPDI) [186,187] was used, as this compound... [Pg.33]

A systematic DMA study was carried out by Marcos et al on a series of aromatic and aliphatic PUs chain extended with diamine functionalised poly(oxypropylene)-tipped poly(oxyethylene) of various molar masses [224]. Four diisocyanates, MDI, 2,4-toluene (TDI), hexamethylene (HMDI) and isophorone (IPDI) were employed. The symmetry/asymmetry of the diisocyanate strongly influenced the dynamic mechanical properties. The symmetric diisocyanates (MDI, HMDI) had more phase... [Pg.65]

The other significant aliphatic diisocyanate, IPDI, is based on isophorone chemistry. Trimerization of acetone gives isophorone (15), which on reaction with HCN affords the /3-cyanoketone (16). Reductive amination of (16) to the diamine (17), followed by phosgenation, gives IPDI (18). [Pg.6668]

Diamines or diols can be used as chain extenders in copolymerization reactions, but urea linkages formed from diamines often lead to polymer insolubility.(28) Poor solubility is avoided by using diols, but this requires a two stage preparation (Scheme 1) because of the disparity in reactivity of alcohols and amines with isocyanates. To form urea and urethane linkages separately, the reaction between isophorone diisocyanate and benzene dimethanol was carried out first in bulk at 115 °C without catalyst (Equation 1). Secondly, reaction between aminopropyl endcapped dimethylsiloxane oligomers and diisocyanate intermediates was effected in THE at room temperature (Equation 2). Completion of the polymerization reaction was established by NMR and infrared spectroscopy.(8)... [Pg.68]
