The reduction of product, bio-based materials substitute products will gradually substitute traditional polyester, polyamide material, and furan type diacid, glycol,
Diamines substrate, because having characteristic similar with phenyl ring, the properties of product of preparation and traditional polyester, polyamide is similar, holds
It is easily acceptable to the market, has broad application prospects.
Furyl platform chemicals are a kind of platform chemicals for deriving from biomass resource, and wherein furfural is at present
One kind of industrialized production has representative furyl platform chemicals.It can be obtained by a series of catalyzed conversions based on furfural
Bifuran and the polymerized monomer with double-active group, include mainly the structures such as Coumarin type glycol and Coumarin type diacid,
Such polymerized monomer can effectively substitute the polymerized monomer extracted via traditional fossil resources, such as bisphenol-A, terephthalic acid (TPA) etc.
Polymeric material monomer.
