The cyclotrimerization of 1-phenyl-2-propyn-1-one (<b>3</b>) with a catalytic amount of secondary amine was first examined in bulk as a model reaction.

Unexpectedly, an exothermic reaction and significant viscosity increase were observed as the monomer conversion of isobutyl vinyl ether (IBVE) up to 90% at 0°C in the absence of a radical initiator. Therefore, we speculated that it was a cationic rather than a radical polymerization and confirmed with the proton trapping agent 2,6-di-tert-butylpyridine. With anhydrous CH₂Cl₂ as a solvent, the molecular weights of the PIBVE are in the range of 5900–8900. With a decrease in the reaction temperature to −20°C, the molecular weight distribution is in the range of 1.74–1.19. Moreover, 2-ethylhexyl vinyl ether (EHVE) and cyclohexyl vinyl ether (CHVE) could also undergo a similar polymerization. A plausible cationic polymerization mechanism is proposed that vinyl ethers are initiated by H⁺ which is generated by the reaction of HFIP and LiI.

However, limited by the low viscosity and the relatively short chemical cross-linking time of the PAM precursor, direct 3D printing of PAM gel with desired mechanical properties remains challenging. This study addresses these challenges by incorporating Laponite nanoclay as a rheological/gelling regulator and nanofiller, alongside N, N′-methylenebisacrylamide (MBA) to accelerate curing. A combination of using Laponite nanoclay and MBA not only alters the viscoelastic characteristics of the precursor and the gelling time but also introduces a significant shear-thinning effect. The formulated PAM-Laponite mixture can be optimized to be adopted by conventional extrusion-based 3D printing to synthesize gel structures with good shape fidelity. The study also shows that the combination of nanoclay physical gelling, PAM chemical cross-linking, and the competitive molecular interactions among different gel compositions allows significant improvement and tunability in the mechanical performances of the resultant gel samples.

The amphiphilic nature of the DSCPs, arising from the spatial segregation of hydrophilic spheres and hydrophobic rods, drives their self-assembly in mixed THF/H₂O solvent systems. The self-assembly behavior can be modulated by adjusting the rod-to-sphere volume ratio, leading to one-dimensional (1D) nanostructures with fiber-like and supercoiled morphologies. The rigidity imparted by both the intrachain crosslinked spherical heads and the hydrophobic rod ensures directional stacking and assembly, facilitating the formation of ordered 1D nanostructures.

In this study, in situ prepared rGO was used due to its thermal stability around the glass transition temperature of bulk PVP (176°C). Based on FTIR results, it was found that the PVP molecules cover many of the residual functional groups of the rGO surface and H–bonding occurs. The H–bonding interaction produces <i>tightly bound</i> PVP on the rGO surface. Unfortunately, the thermal signature of the <i>tightly bound</i> segments of PVP on the rGO was weak and not directly quantifiable from the TMDSC thermograms of the composite samples. This was in contrast to the cases for either poly(methyl methacrylate) (PMMA) or poly(vinyl acetate) (PVAc) on silica where the thermal activity (peaks) from the tightly bound polymer were quantifiable. Therefore, a different analysis was conducted to indirectly estimate the amount of <i>tightly bound</i> PVP absorbed on the rGO from the “<i>missing</i>” PVP thermal signal. Linear regression of the data fitted to this model provided an estimate of the amount of <i>tightly bound</i> PVP on the rGO surface as 0.84 ± 0.03 (SD) mg PVP/m² rGO.

This result was also similar in amount to the previously reported H–bonded systems mentioned above on silica, where the signature of a <i>tightly bound</i> polymer was directly observed, and the <i>tightly bound</i> amount was on the order of 1 mg/m² (for PMMA, 1.21 and PVAc, 0.78 mg/m²).

In order to enhance the mechanical properties and compatibility of PLA with TPO(NV), TPOGS (TPO grafted with glycidyl methacrylate (GMA) and styrene (St) as a co-grafting monomer) graft copolymer was prepared by melt grafting and used as a compatibilizer, in combination with the small-molecule additive dibutyl itaconate (DBI). PLA/TPOGS/DBI blends with varying DBI contents were prepared, and the synergistic compatibilization effects of the TPOGS and DBI on the PLA/TPO blends were investigated. The impact of the DBI content on the compatibility, crystallization behavior, rheological properties, mechanical properties, and microstructure of the PLA/TPOGS blends was also investigated. The results confirmed that GMA and styrene were successfully grafted onto the TPO elastomer, and the compatibility of the grafted elastomer with PLA was improved. Furthermore, DBI was found to react with the main chains of PLA or TPO(NV) through double bonds, forming chemical links and acting as a “bridge,” which, in synergy with the graft copolymer, further enhanced the compatibility between PLA and TPO(NV). As the DBI content increased, the glass transition temperature (<i>T</i>\u0000 _{\u0000 <i>g</i>\u0000}) difference between PLA and TPO(NV) significantly decreased from 95.06°C (DBI = 2.5 wt%) to 82.53°C (DBI = 12.5 wt%). Due to the plasticizing effect of DBI, the melt flow index of PLA/TPO(NV) gradually increased with the DBI content. The addition of DBI did not affect the crystallization process of the TPO(NV) elastomer, with the crystallization during cooling forming a PP-α crystalline phase, and the degree of crystallinity remained relatively constant, with the crystallization temperature maintained around 104°C. DBI had a stronger influence on the PLA component within PLA/TPOGS/DBI blends, as higher DBI content led to increased PLA crystallinity and a significant shift in the cold crystallization temperature from 122.54°C to 115.05°C. This indicates that the plasticizing effect of DBI primarily impacts the PLA phase within the PLA/TPO(NV) blend. The mechanical properties of PLA/TPOGS/DBI blends initially increased but later decreased as the DBI content continued to increase. At a DBI content of 10 wt%, the notched impact strength and elongation at break reached their highest values, 1.3 times and 7 times higher, respectively, than those of the PLA/TPOGS blend without DBI.</p>\u0000 </div>","PeriodicalId":16888,"journal":{"name":"Journal of Polymer Science","volume":"63 8","pages":"1908-1923"},"PeriodicalIF":3.9,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
