| titleOfInvention | Radiation-curable polyester diol and preparation method and application thereof |
| abstract | The invention relates to a radiation-curable polyester diol and a preparation method and application thereof, wherein the number average molecular weight of the radiation-curable polyester diol is 300-6000, and the structural formula of the radiation-curable polyester diol is as follows: (ii) a Wherein R is 1 、R 2 Is a linear, cyclic or branched structural unit consisting of 1-12 saturated carbon atoms; m + n is an integer of 1 to 50. The radiation-curable polyester diol branched chain provided by the invention contains at least one unsaturated double bond, and the unsaturated double bond in the polymer branched chain is crosslinked under the conditions of heat and radiation, so that the mechanical property, the chemical resistance and the dimensional stability of a product are improved; and because the double bond crosslinking density is controllable, the product has higher comprehensive physical and chemical properties such as higher tensile strength, larger modulus, better solvent resistance and better high temperature resistance. In addition, the radiation-curable polyester diol provided by the invention has a branched chain due to a branched chain, so that the crystallization temperature is reduced, and the use is more convenient. |
