Narrow molecular weight polycaprolactone diol with molecular weight of 2000 and preparation method thereof

The invention relates to narrow-molecular-weight polycaprolactone diol with the molecular weight of 2000. The narrow-molecular-weight polycaprolactone diol is prepared from diol monomers, epsilon-caprolactone, a catalyst and an antioxidant, wherein the diol monomers are one or more of ethylene glyco...

Beschreibung
Zusammenfassung:	The invention relates to narrow-molecular-weight polycaprolactone diol with the molecular weight of 2000. The narrow-molecular-weight polycaprolactone diol is prepared from diol monomers, epsilon-caprolactone, a catalyst and an antioxidant, wherein the diol monomers are one or more of ethylene glycol and 1, 4-butanediol, and the purity of the ethylene glycol and the purity of the 1, 4-butanediol are greater than or equal to 99.99%; the epsilon-caprolactone is epsilon-caprolactone which is produced domestically and has the purity of more than or equal to 99.99%; the catalyst is one or more of titanium isopropoxide, stannous octoate and zinc naphthenate with the purity being greater than or equal to 99%; the antioxidant is one or more of phenyl triphosphite and pentaerythritol ester with the purity of more than or equal to 99%. The narrow-molecular-weight polycaprolactone diol resin with the molecular weight of 2000 is synthesized into elastic resin and a prepared elastic coating, the low-temperature-resistant
