Injectable and photocurable macromonomers synthesized using a heterometallic magnesium-titanium metal-organic catalyst for elastomeric polymer networks.

Injectable and photocurable biomaterials are receiving a lot of attention due to their ease of application syringe or dedicated applicator and ability to be used in laparoscopic and robotic minimally invasive procedures. The aim of this work was to synthesize photocurable ester-urethane macromonomers using a heterometallic magnesium-titanium catalyst, magnesium-titanium(iv) butoxide for elastomeric polymer networks. The progress of the two-step synthesis of macromonomers was monitored using infrared spectroscopy.

Interfacial Polarization in Thermoplastic Basalt Fiber-Reinforced Composites.

The aim of this work was to study the interfacial behavior of basalt-fiber-reinforced thermoplastic blends of polypropylene and poly(butylene terephthalate) (PP/PBT). We examined the effect of two compatibilizers and two basalt fiber (BF) sizings: commercial (REF) and experimental (EXP). Differential scanning calorimetry was used to assess the influence of BFs on the phase structure of obtained composites.

Bio-Based PBT-DLA Copolyester as an Alternative Compatibilizer of PP/PBT Blends.

The aim of this work was to assess whether synthesized random copolyester, poly(butylene terephthalate--butylene dilinoleate) (PBT-DLA), containing bio-based components, can effectively compatibilize polypropylene/poly(butylene terephthalate) (PP/PBT) blends. For comparison, a commercial petrochemical triblock copolymer, poly(styrene--ethylene/butylene--styrene) (SEBS) was used. The chemical structure and block distribution of PBT-DLA was determined using nuclear magnetic resonance spectroscopy and gel permeation chromatography.
