The compounds 1,4-butanediol, succinic anhydride, and NCC were used in this study to successfully synthesize poly(butylene succinate)-grafted NCC (PBS-g-NCC) nanocomposites via polymerization in situ, and subsequent analyses clearly showed that this approach increased the thermal stability and degree of crystallinity of the product.
The ingredients could potentially be harmful to some animals: Experts say that cats and dogs shouldn't ingest any caffeine, which is generally toxic for pets, and a 2014 report from the World Health Organization found that there was no medical or veterinary use for 1,4-butanediol.
Therefore, in this study, the DMF-based polyurethanes were synthesized using four different types of polyols with/without MPD component, 1,4-butanediol and 1,6-hexanediol as chain extenders, and MDI as diisocyanate.
The DESs were prepared at specific ratios of choline chloride to the hydrogen donor (i.e., 1,4-butanediol, glycerol, and lactic acid; Table 1).

Thus, this study aimed to investigate in vitro the association between HA crosslinked with 1,4-butanediol diglycidyl ether (BDDE), which was structured in microparticles (mHA-BDDE) and sponges (sHA-BDDE), with PRP as composite scaffolds for growth factor release, the proliferation of human adiposederived mesenchymal stem cells (h-AdMSCs) and differentiation by the osteogenic marker alkaline phosphatase (ALP).
1,4-Butanediol (BDO) and propylene glycol were provided by Tianjin Bodi Chemical Co., Ltd.
Moreover, new applications such as 1,4-Butanediol (BDO), plasticisers, and polyesters will open up huge opportunities in the Global Bio-succinic Acid Market during the forecast period.
Lanxess and Genomatica have started running a production campaign of bio-based PBT in Lanxess's world-scale production plant, using 20 metric tons of bio-based 1,4-butanediol made with Genomatica's commercially-proven process.
* Bio 1,4-Butanediol: Myrianes bio BDO, produced From bio Succinic acid is a drop in for all BDO applications.
[20] proposed an intercalation method in solution, as PU prepolymer was inserted into the MMT intergallery in solution conditions followed by a curing procedure with 1,4-butanediol. To further improve the properties of PU/clay nanocomposites, alternate functional modifiers which can react with polymer are being used to prepare polymer/clay nanocomposites.
BASF will increase its global capacities: for producing the chemical intermediate 1,4-butanediol (BDO) and the BDO derivative PolyTHF (chemical name: polytetramethylene ether glycol, PTMEG) within the coming two years.
