Fringed micelle crystallite formation

In this study more attention was paid to the possible formation of fringed micelle crystallites by rigid segments of RIM formulations. These crystallites could be considered to be an important factor inhibiting the mobility of the reactive groups and consequently causing the deviations from the straight line dependence of the second order reaction kinetic plot. [Pg.65]

Incorporating a plasticizer into the RIM formulations as a nonvolatile residual solvent should at least partially inhibit the formation of the fringed micelle crystallites and thus depress the build-up of physical crosslinks by die aggregation of crystallites. [Pg.66]

The urethane formulation presented in the paper was based on 1,6 hexamethylene diisocyanate (HDI), an aliphatic diisocyanate, and on tripropylene glycol (TPG) prepolymer, cured with a medium molecular size triol with an equivalent weight per OH of 180 (mol. wt. 540). This formulation did not have rigid segments for formation of fringed micelle crystallites as physical crosslinks. Therefore, the kinetic plot of the adiabatic reaction data resulted in a straight line without any deviation point. [Pg.76]

Figure 3.6). This theory known as the fringed micelle theory or fringed crystallite theory helped to explain many properties of crystalline polymers but it was difficult to explain the formation of certain larger structures such as spherulites which could possess a diameter as large as 0.1 mm.
