“…Isosorbide is a biomass-based diol prepared from sugar and has been industrially produced with large yield and low price. With the advantages of chiral rigid ring structure and nontoxicity, incorporating isosorbide into polyesters to improve their stability and glass transition temperature has become a hot research topic recently. − Since the hydroxyl groups of isosorbide are secondary with relatively low reactivity compared to 1,4-butanediol, conventional CP by copolymerization with terephthalic acid (TA)/dimethyl terephthalate (DMT) usually affords poly(butylene- co -isosorbide terephthalate) (PBIT) copolyesters with low molecular weights and low incorporation amounts of isosorbide. , The molecular weights of copolyesters can be increased using terephthaloyl chloride as monomer in a solution polymerization process, which is hard for industrialization. Another way is to modify the isosorbide by introducing high reactivity groups. − For example, Duchateau et al reported the synthesis of PBIT copolyesters with high molecular weights via a solid-state polymerization method from a macrodiol monomer with isosorbide in the middle segment .…”

Poly(butylene terephthalate) (PBT) is an important engineering plastic with good mechanical properties. We report herein the incorporation of biobased isosorbide into PBT by a green in situ cascade polycondensation-coupling ring-opening polymerization (PROP) method via the melt polymerization of commercially available isosorbide as initiator and cyclic oligo(butylene terephthalate)s (COBTs) as monomer. By varying the feeding weight ratio of isosorbide to COBTs, poly(butylene-coisosorbide terephthalate) (PBIT) copolyesters with different content of isosorbide (5−20%) were synthesized. The structure of the PBIT copolyesters was characterized by 1 H quantitative and 2D 1 H− 1 H gCOSY NMR spectra. Kinetics studies confirm the PROP mechanism, which shows the advantage of high atom economy (89−99%). Property investigation of the sustainable PBIT copolymers shows that their thermal decomposition temperature increased slightly compared to PBT homopolymers, and the glass transition temperature increases with isosorbide content, while the melting and crystallization temperatures, crystallinity, and storage modulus decrease accordingly. Our PROP method provides a facile method for the synthesis of biodegradable and sustainable PBIT copolymers, with improved properties that could extend their applications in engineering plastics.

“…[ 76 , 77 , 78 , 79 , 80 , 81 , 82 ]. For example, rigid foams have a low density (30–58 kg·m −3 ) [ 83 ] and a high content of closed cells, which gives them a low thermal conductivity (0.0267–0.034 W m −1 ·K −1 ) [ 84 ]. These properties make them good candidates for exterior insulation, heat retention, and, ultimately, energy savings [ 85 ].…”

A Review of Rigid Polymeric Cellular Foams and Their Greener Tannin-Based Alternatives

This review focuses on the description of the main processes and materials used for the formulation of rigid polymer foams. Polyurethanes and their derivatives, as well as phenolic systems, are described, and their main components, foaming routes, end of life, and recycling are considered. Due to environmental concerns and the need to find bio-based alternatives for these products, special attention is given to a recent class of polymeric foams: tannin-based foams. In addition to their formulation and foaming procedures, their main structural, thermal, mechanical, and fire resistance properties are described in detail, with emphasis on their advanced applications and recycling routes. These systems have been shown to possess very interesting properties that allow them to be considered as potential substitutes for non-renewable rigid polymeric cellular foams.
