Preparation of l-Lactide/3-Glycidyloxypropyltrimethoxysilane Copolymeric Materials with Various Catalysts

Abstract

Copolymerization reactions of 3-glycidyloxypropyltrimethoxysilane (GPTS) with L-lactide (LLA) at 100°C for different time intervals are performed by various catalysts such as zirconium perfluoroheptanoate, and commercially available Tin(II) chloride (SnCl 2 ) and sodium trimethylsilanolate (NaOSiMe 3 ). Homo-and copolymers are characterized by FTIR, 1 H-and 13 C-NMR spectroscopies, electrospray ionization mass spectroscopy, thermal gravimetric analysis, differential scanning calorimetry and gel permeation chromatography. All selected catalysts are effective in ROP of monomers. Especially, SnCl 2 is more reactive catalyst in the copolymerization of LLA/GPTS. The structure of final product is found as random copolymers.

Copolymerization reactions of butadiene monoxide with 3‐glycidyloxypropyltrimethoxysilane and styrene oxide and their glycol derivatives

“…The promising applications of the homo‐polymers led researchers to investigate their copolymers deeply. In our previous works, we have reported the copolymerization reactions of GPTS with lactide . Recently, block copolymers of polybutadien oxide–polyethylene oxide (PBuO–PEO) were synthesized and used in the design of efficient nanocarriers for cancer chemotherapy …”

High thermal resistance amorphous copolyesters synthesized from bio‐based 2,5‐furandicarboxylic acid

“…In Figure 1, 1 H-NMR spectra and characteristic peak assignment of PBSCFs were used to identify the chemical structures, our previous works [27][28][29][30] and some related references 34,35 are also referred. It was noted from the enlarged spectrum that the signal for CH (f) in the furan ring split into two overlapping doublets, showing at 7.10-7.13 ppm.…”

Preparation and characterization of TAMP/TIMP-Ti and Zr compounds and their catalytic activity over propylene oxide and Ɛ-caprolactone

“…However, as can be seen in Figure 6, the GPC chromatogram of the PO polymer prepared at 75 °C with Ti-TAMP showed bimodal molecular weight distribution. The first peak in Figure 6 has weight average molecular weight Transition metal compounds carry out ROP of ε-CL and PO via a coordination-insertion mechanism [26][27][28][29][30][31][32][33]. For example, the polymerization mechanism of ε-CL can be shown in …”
