Materials. Bisphenol A-epichlorohydrin condensate 1 (Eponol-55-B-40, Shell Chemical Co.) was precipitated from chloroform solution by addition of methanol three successive times prior to utilization. Polymer films of 1.5 and 15 pm were cast onto glass plates from chloroform solution.

Epoxies are made from Bisphenol A and epichlorohydrin. They are tough, resistant to heat, and have good adhesive properties. They can be mixed on-site by adding a catalyst and filler to the already linked Bisphenol A/epichlorohydrin that causes the cross-linking and the sec in thermoset.

The IPNs prepared were composed of a rubbery polyurethane and a glassy epoxy component. For the polyurethane portion, a carbodiimide-modified diphenyl-methane diisocyanate (Isonate 143L) was used with a polycaprolactone glycol (TONE polyol 0230) and a dibutyltin dilaurate catalyst (T-12). For the epoxy, a bisphenol-A epichlorohydrin (DER 330) was used with a Lewis acid catalyst system (BF -etherate). The catalysts crosslink via a ring-opening mechanism and were intentionally selected to provide minimum grafting with any of the polyurethane components. The urethane/epoxy ratio was maintained constant at 50/50. A number of fillers were included in the IPN formulations. The materials used are shown in Table I.

The unreacted terminal epoxide groups can react with other diamine molecules to form a rigid network polymer. In this reaction the functionality of the bisphenol A-epichlorohydrin prepolymer 1-20 will be 2 since hydroxyl groups are not involved and the functionality of each epoxide group is one. 

In principle, the knowledge of the momentary concentrations of the active species is not necessary to determine the rate constants (cf. Fig. 14) because both kp and kj can be simultaneously determined by solving equations describing the non-stationary kinetics, as was shown for the cationic polymerization of sts rene by Peppra (partial solution) and for the polymerization of a-epichlorohydrin (complete kinetic solution). 

Two components are required, which are mixed just prior to use. The prepolymer, in which the cross-linkable epoxide functions reside, is made from epichlorohydrin and /s-phenol A. Epichlorohydrin in turn is derived from allyl chloride (Eq. 21.24). 

Compare the properties of epoxy resins based on bisphenol A-epichlorohydrin with those based on epoxides that can be made without the use of epichlorohydrin.
