The first step involved the preparation of the adduct of trimethylol propane and tolylene diisocyanate. |

Traditionally, tolylene diisocyanate has been used for the production of flexible slabstock foams for the last 40 years or so. |

Tolylene 2,4-diisocyanate and bisphenol A will be used as reactants to produce novel epoxy-layered silicate nanocomposites. |
