Embodiment 1

[0022] Embodiment 1: one of the synthetic method of unsaturated polyester resin:

[0023] Mix 2.0 moles of maleic anhydride, 2.0 moles of phthalic anhydride, 0.2 moles of dimer acid, 2.2 moles of ethylene glycol, and 2.1 moles of diethylene glycol, put them into a 250ml three-necked flask with a water separator, and place them in a silicone oil bath , electric stirring, heating up to 150°C, melt polymerization in nitrogen atmosphere for 40 minutes, then raising temperature to 180°C, melt polymerization in nitrogen atmosphere for 120 minutes, then raising temperature to 200°C, melt polymerization in nitrogen atmosphere for 30 minutes. When the distilled reaction water reaches 80% of the theoretical amount, the polymerization is stopped, the temperature is lowered to 150° C., and poured out. After cooling, a light yellow transparent viscous liquid unsaturated polyester resin is obtained.

Abstract

The invention uses a melt phase polycondensation method, uses dimer acid as a reaction monomer for the first time, and performs copolymerization on the dimer acid and several monomers in the group consisting of ethylene glycol, propylene glycol, diethylene glycol, neopentyl glycol, polyethylene glycol, fumaric acid, maleic anhydride, adipic acid, phthalic anhydride and m-phthalic acid to obtain an unsaturated polyester resin with excellent combination properties and low cost. The resin is expected to serve as the matrix resin of medical intrabony fixing materials, tissue engineering support materials, bone tissue temporary substitutes, environment-friendly adhesives, environment-friendly fiber glass reinforced plastics, environment-friendly paints, disposable tableware, packaging materials, shopping bags, garbage bags, pharmaceutical coatings, or capsules, pharmaceutical slow-release (controlled-release) materials, agricultural mulching film and the like.

Description

technical field [0001] The invention relates to a chemical synthesis environment and biodegradable polymer materials and methods. Using several monomers such as ethylene glycol, propylene glycol, diethylene glycol, neopentyl glycol, polyethylene glycol, fumaric acid, maleic anhydride, adipic acid, phthalic anhydride, isophthalic acid, etc. One is the basic raw material, which can be co-polymerized with dimer acid to obtain unsaturated polyester resin with excellent comprehensive performance and low cost. This kind of resin can be used as medical bone internal fixation material, tissue engineering scaffold material, bone tissue temporary substitute, drug coating or capsule, drug sustained release material, UV-curable ink, UV-curable paper coating, environment-friendly FRP, Adhesives, base materials for environment-friendly UV-curable or room-temperature-curable coatings. technical background [0002] Existing light-curing coatings all need to use toxic coating additives and...
