thermal polymerization

[′thər·məl pə‚lim·ə·rə′zā·shən]
(chemical engineering)
A thermal, petroleum refining process used to convert light hydrocarbon gases into liquid fuels; paraffinic hydrocarbons are cracked to produce olefinic material which is concurrently polymerized by heat and pressure to form liquids, the product being known as polymer gasoline.

Based on the aforementioned results, redox and thermal polymerization were carried out at O/W and W/O type emulsions, respectively.
As shown in Scheme 1, possible chemical reactions are thermal pyrolysis, thermal oxidation, and thermal polymerization according to detected compounds in Table 1.

(57) According to Endo, alcohols with acidic nature would have a favorable effect on the ring-opening reaction, while neutral compounds such as 1.3-propanediol cause a retardation and thermal polymerization is induced at relatively higher temperatures.
prepared functionalized graphene oxide with reactive epoxy groups to obtain polymer nanocomposites via in situ thermal polymerization, and the mechanical, electrical, and thermal properties of the epoxy nanocomposites are efficiently enhanced [10].
Regarding the resins' behavior when submitted to a lack of hydration (2nd reading), and to an ensuing rehydration (3rd reading), it was observed that in the conventional thermal polymerization group, the values for nanohardness were very similar when using the standard time of polymerization, except for a few variations, as can be seen in Graph 1.
In order to get a better feel about how narrow the polydispersity values are in NMRP, values from thermal polymerization of styrene (in the absence of initiator and nitroxide), as well as thermal NMRP (nitroxide-mediated polymerization of styrene in the absence of initiator) are also presented in Figure 17b and c.

This was a polymer of 2,3-dimethylbutadiene produced by thermal polymerization at 30-70 [degrees] C in a process lasting from 2-6 months!
In those IPNs, the urethane was formed under thermal polymerization and the acrylate by photo-polymerization.
Then, the particles are captured on the surface of polymer microspheres during the processes of thermal polymerization. Compared with conventional preparation techniques, the polystyrene/detonation nanographite (PS/DNG) composites could be obtained in a one-pot synthesis with the absence of common stabilizers via Pickering emulsion [28-30].
