“…Polyamide12 (PA12) is one of the important engineering plastics with a broad range of applications including oil resistant tubes for automotive, cables, food packaging films and powder coatings for metals. For the improvement in toughness of the PA12, blending it with various rubbers such as styrene/ethylene-butylene/styrene block (SEBS) rubber [28], epoxidized natural rubber (ENR) [29] and natural rubber [30] has been explored However, this decreases the tensile modulus and strength. Polyolefin elastomer (POE), a commercially important rubber developed by Dow Elastomers under the brand name Engage ® , has good processibility and thermo-oxidative resistance.…”

Small amounts of glycidylisobutyl polyhedral oligomericsilsesquioxane (G-POSS) (up to 10 phr) were added into a immiscible polyamide12 (PA12)/polyolefin elastomer (POE) blend (70 wt%/30 wt%) by simple melt mixing. The effects of the G-POSS on phase morphology and mechanical properties were investigated by FE-SEM, tensile testing, Izod impact test and dynamic mechanical analysis. FE-SEM analysis revealed that domain size of the dispersed POE phase in matrix PA12 is decreased significantly by adding the G-POSS, indicating a compatibilization effect of the G-POSS for the immiscible PA12/POE blend. The PA12/POE blend compatibilized with POSS showed simultaneous enhancement in mechanical properties including tensile modulus, strength and toughness. Further, thermally triggered shape memory effect was observed in this compatibilized blend.

“…LCPA mainly includes PA11, PA12, PA1212, and PA1313. [4][5][6][7] Except for possessing most of the general properties of PAs, LCPAs also show good flexibility, low water absorption, and good dimensional stability. The global market size of LCPAs exceeded USD 1.1 billion in 2019, with an annual production of over 92 000 tons.…”

The thermal stability and reactivity of organophosphorus flame-retardants play a critical role in synthesizing copolymerized flame-retardant polyamides. Herein, this work successfully synthesizes a flame-retardant CEPPA-DDA salt (CDS) with both good thermal stability and high reactivity by reacting 2-carboxyethyl phenyl phosphonic acid (CEPPA) with 1,12-dodecanediamine (DDA). Flame-retardant polyamide 1210 (FRPA) is further prepared by copolymerizing the CDS, DDA, and sebacic acid (SEA). The test results show that the introduction of CDS can significantly improve the flame-retardant properties of FRPA. Specifically, the flame-retardant polyamide 1210 (FRPA-7) with 7 wt% CDS addition can reach V-0 grade according to UL-94 standard, accompanying limiting oxygen index value of 30.2% and tensile strength of 38.62 MPa. Compared with pure polyamide 1210, the peak heat release rate and total heat release rate of FRPA-7 reduce by 24.11% and 9.40%, respectively. This study provides a simple strategy to prepare flame-retardant polyamides with high flame retardancy and good mechanical properties, which are expected to show great potentials in future industrial applications.

Role of sol-gel interaction with anisotropic nanoclay in raw natural rubber (NR) for offering higher mechanical reinforcement than isotropic nano zinc oxide was reported in this article. Experiments were carried out on four different grades of NR, having equal Mooney viscosity but different gel contents (toluene insoluble fraction), with commercial grades of nanofillers. In raw NR, the green strength was found to be influenced by higher apparent viscosity instead of higher gel content. In unvulcanised nanocomposites, however, the reinforcement was subjected to interaction between the nanofillers and the sol fraction (toluene soluble fraction, major part of the matrix) of NR. The mixing energy was decreased by approximately 2.9% for nanoclay (Cloisite 30B) and 4.4% for nano zinc oxide addition, whereas the gel content has increased upon addition of Cloisite 30B and nano zinc oxide by 12% and 49%, respectively. The ability was found higher with nano zinc oxide due to its isotropic shape and lower overall size than Cloisite 30B. Conversely, higher sol concentration of Cloisite 30B along with higher filler volume fraction offered higher mechanical reinforcement in both high and low gel grades of NR. The fact was established from extensive studies on morphology, filler crystallography, gel content, and viscoelastic responses.
