Catalysis of deblocking and cure reactions of easily cleavable phenol blocked polyisocyanates with poly(polytetrahydrofuran carbonate) diol

Abstract Carbon black can function as an inhibitor or as an accelerator of oxidation and cure of rubber and of other polymers. The inhibiting action of carbon black on the oxidation of unvulcanized cold rubber appears to be related to, if not the cause of, the increased reinforcement of the heat-treated stock. In general, the effect of carbon black on the oxidation of cold rubber and natural rubber is the same. With a more complete understanding of the role of carbon black in polymer oxidation and cure reactions, it should be possible to control the behavior of carbon black so that advantage can be taken of its inhibiting and accelerating properties in prolonging the life and increasing the usefulness of rubber goods.

Reversible Processes

We are combining thermal analysis with the ability of thermal waves to give sub-surface imageing at sub-micron resolution. Our aim is that the image contrast will be determined by the “modulated-temperature differential scanning calorimetry” peak (M-T DSC) or feature chosen according to the particular component of the specimen that is of interest. As described elsewhere, this will allow us to distinguish in the image between reversible processes such as amorphous-to-glass transitions, from recrystallisations, cure reactions and other irreversible processes within the polymer.The SThM probe gives micron-resolution images whose contrast is determined by spatial variations in thermal properties. Either the temperature at any point is held constant, or we generate and detect evanescent thermal waves whose penetration depth depends on the frequency chosen.The evidence is that a 1 μm-radius probe in air will give a lateral resolution of ca. 200 nm, with a depth detection of a few μm.
