- a tricyclodecane dimethanol modified lactone polymer is obtained. Is obtained.
- the number of moles of the lactone added per mole of tricyclodecane dimethanol [m + n in the general formula (I)] is 1 to 100, preferably 1 to 20.

Not so desirable.
- the number of moles of the lactone added is smaller than 1, the effect of the lactone addition is not obtained.
- the reaction system containing the lactone and the initiator is required Heat to 50-220, preferably 100-200. At low temperatures the reaction rate is slow and impractical, and at too high temperatures pyrolysis occurs and is not preferred. It is preferable to use a catalyst for this reaction.

- the amount of the catalyst used is from 0.01 to 200 ppm, preferably from 0.1 to 50 ppm, based on the total weight of the starting materials excluding the solvent, that is, tricyclodecanedimethanol and lactones. If the use amount of the catalyst is more than 200 pm, the resin is likely to be colored, and the stability of the product is adversely affected. Conversely, if the amount of the catalyst used is less than 0.01 ppm, the reaction rate of the ring-opening addition polymerization of lactones becomes extremely slow, which is not preferable.
- the reaction tends to be colored when the reaction is performed in an air atmosphere
- the reaction is preferably performed in an inert atmosphere such as nitrogen.
- the reaction may be carried out without solvent, but in an inert solvent without active hydrogen such as toluene, xylene, methylethylketone, methylisobutylketone, etc. Is preferred.
- the use of the solvent has the effect of reducing the viscosity of the reaction solution in the system after the completion of the reaction, and also facilitates temperature control during the reaction.
- a solvent having an ester bond is not preferred. This is because transesterification occurs with the ester group of the polyprolactone during the reaction, and a lactone polymer containing a compound other than tricyclodecanedimethanol may be formed.
- the amount of inert solvent used is from 0 to 80% by weight, preferably from 0 to 50% by weight, based on all starting materials including the solvent.
- the amount of the solvent is more than 80% by weight, the concentration of the reaction component is lowered, and the rate of ring-opening addition polymerization of lactones is undesirably reduced.
- the starting materials tricyclodecane dimethanol, lactones, and catalyst are charged into a reactor, and then the temperature is raised to the above-mentioned temperature range to cause addition polymerization of the lactones.
- the progress of the addition polymerization of lactones is determined by measuring the concentration of the remaining lactones in the reaction mixture by gas chromatography, and the time when the concentration of the lactones becomes 1% or less is usually regarded as the end point of the addition polymerization. Even if a solvent is used, it is not always necessary to remove the solvent from the product after the addition polymerization.
- Polyurethane using the novel lactone polymer of the present invention can be used as a polyurethane dispersion by subjecting it to aqueous treatment.
- Table 1 shows the properties of the polymer (resin) obtained in each example.
- demineralized water 383.4 parts was gradually added to obtain an oil-in-water type urethane prevolimer dispersion, and then 33.22 parts of isophoronediamine and 299.0 parts of demineralized water were added at 10 to add the prevolimer chain.
- the extension was performed to obtain an aqueous polyurethane resin having a solid content of 30%, a viscosity of 150 mPas / s / 25, and an average particle diameter of 5 / m.
- the novel lactone polymer of the present invention produced by using tricyclodecane dimethanol as an initiator is a compound useful as a raw material for polyurethane having excellent heat resistance, weather resistance, and chemical resistance.
- Polyurethane applications include thermoplastic urethane elastomers, thermosetting urethane elastomers, urethane foams, adhesives, sealing agents, paints, etc.When used in such applications, good physical properties can be obtained.
