A method of producing an oligofuran moiety-containing polycarbosilane, the method including a polymerization step of reacting a dihydrosilyloligofuran compound with a diene compound and / or diyne compound in the presence of ahydrosilylation catalyst in which method the dihydrosilyloligofuran compound being a compound having a 2- to 256-mer of a furan ring and a hydrosilyl group at the α-position of each of both terminal furan rings of the 2- to 256-mer of the furan ring.

This invention relates to the field of bio-based injection molding technology, specifically to a bio-based injection molding compound and its production process, comprising the following raw materials in parts by weight: 80-95 parts matrix resin, 4-6 parts modified reinforcing components, 2-3 parts bio-based crosslinking components, and 2.5 parts bio-based functional additives. The matrix resin is based on polylactic acid (PLA), compounded with polybutylene furanate and polyhydroxyalkanoates to form a ternary bio-based polyester system. This system compensates for the brittleness of PLA at the matrix level, improving elongation at break. The addition of modified reinforcing components enhances the material's rigidity and heat resistance through nanoscale reinforcement. Furthermore, the ionic liquid modification improves the compatibility with the matrix interface, preventing the mechanical properties from decreasing due to reinforcing phase agglomeration. Nanocellulose replaces traditional glass fiber reinforcement, avoiding wear on the screw and mold, and extending equipment lifespan.

The object of the present invention is to provide a polyester that can be manufactured from biomass-derived raw materials and has excellent heat resistance, gas barrier properties, and blow moldability, a polyester composition containing the same, and a bottle using the same that has excellent heat resistance, gas barrier properties, and impact resistance. [Solution] A polyethylene furanoate having an intrinsic viscosity of 0.95 dl / g or more and 1.50 dl / g or less. However, the intrinsic viscosity is measured at 30°C using an Ubbelohde viscometer after dissolving 0.25 g of the polyethylene furanoate in 50 ml of a mixed solvent of phenol / 1,1,2,2-tetrachloroethane = 50 / 50 (weight ratio) (Huggins constant is assumed to be 0.32).

This polyethylene furanoate has an intrinsic viscosity of 0.95-1.50 dl / g. Said intrinsic viscosity is measured (the Huggins constant is defined as 0.32) at 30°C by using a Ubbelohde viscometer, after dissolving 0.25 g of the polyethylene furanoate in 50 ml of a solvent mixture of phenol / 1,1,2,2-tetrachloroethane=50 / 50 (weight ratio).
