“…The T c of TPU hard phase also shifted toward higher temperatures when TPU was blended with ENR without filler (F0). This is attributed to the vulcanized ENR droplets, dispersed in the TPU matrix, acting as nucleating agents and sequentially accelerating the crystallization of TPU [51,52].…”

“…The most profound TPVs were based on blends of PP and ethylene propylene diene rubber (EPDM). Several additives, such as resol resin, coagent‐assisted peroxides and vinyltrialkoxysilane, had been employed to crosslink the EPDM in PP/EPDM blends . Another research hot spot was TPVs based on blends of PP and ethylene‐octene copolymer (EOC).…”

The SEBS/PP thermoplastic vulcanizates (TPVs) were prepared by melt blending. Di‐tert‐butyl peroxide (DTBP) was used as the curing agent in combination with trimethylopropane trimethacrylate (TMPTMA) and poly(styrene‐b‐butadiene‐bstyrene) (SBS) as the coagents for the curing process. The synergistic effect of TMPTMA and SBS on the structure and properties of TPVs was studied by means of FT‐IR, DSC, torque rheometer, and universal testing machine. Both SEBS and PP crosslinked and the network structure formed under the participation of TMPTMA and SBS. Compared with the sole addition of the coagent, simultaneous loading of both TMPTMA and SBS could provide the TPVs with better solvent‐resistance and excellent mechanical properties. The crosslinking mechanism of the TPVs was also proposed. The slight lower value of Tm for the TPVs indicated the improved miscibility between PP and SEBS due to the crosslinking reaction. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

“…It can be seen that there exists an obvious turning point (TP) that separates the two crystallization stages. During the primary crystallization stage, the n 1 values for all samples at various cooling rates were above 4, indicating that the crystallization followed a three‐dimensional growth mechanism . Z c is known as an estimate of the crystallization rate of the samples, and both Z c 1 and Z c 2 increased as the cooling rate increased from 2.5 to 40°C/min, suggesting the overall crystallization rate was increased.…”

In this work, solution blending was used to prepare series of polyvinylidene fluoride (PVDF)/graphene nanoplatelet (GNP) nanocomposites to investigate the effect of GNP content on the formation of filler network structure. Thermorheological complexity was observed with increasing GNP content, which was substantiated by morphological observation. Three classical thermal conduction models were adopted and compared with the measured thermal conductivity as a function of GNP loading, among which the Agari model presented the most reasonable prediction. A four‐parameter model was proposed to reflect the cooling behaviors of the PVDF/GNP composites with the aid of an in‐situ temperature measurement, suggesting the formation of GNP network structure in the composites. The incorporation of GNP showed an obvious nucleating effect on the crystallization of PVDF without altering its crystal form. Owing to the competition between spatial effect and heterogeneous nucleation, both crystallization rate and enthalpy achieved the maximum values when 6% GNP was added.
