Definitions
- the invention relates to aliphatic polycarbonate homopolymers and copolymers which are obtained by ring-opening homo- or copolymerization of cyclic carbonates
- Double metal cyanide (DMC) catalysts for the ring-opening polymerization of oxygen-containing, cyclic monomers have long been known.
- DMC catalysts have found commercial interest above all for the production of polyether polyols by polyaddition of epoxides to starter compounds having active hydrogen atoms (see, for example, US Pat. Nos. 3,404,109, 3,929,505, 3,941,849 and 3,941,849) -A 5 158 922), since the use of the DMC catalysts brings about a reduction in the proportion of monofunctional polyethers with terminal double bonds, so-called monools, in comparison to the conventional production of polyether polyols by means of alkali catalysts.
- DMC catalysts e.g. in US-A 5 470 813, EP-A 700 949, EP-A 743 093, EP-A 761 708, WO 97/40086, WO 98/16310 and WO 00/47649 also have an extremely high activity and enable the production of polyether polyol at very low catalyst concentrations (25 ppm or less), so that it is no longer necessary to separate the catalyst from the finished product.
- DMC catalysts also enable the homo- and copolymerization of other oxygen-containing, cyclic monomers, such as e.g.
- Aliphatic polycarbonate homo- and copolymers are suitable as additives for thermoplastic systems.
- Aliphatic OH-functional polycarbonates are also widely used as hydroxyl components for the construction of polyurethanes and polyurethane-urea elastomers. Common methods of making aliphatic
- Polycarbonates are transesterifications of diols with dialkyicarbonates from short-chain against alcohols, with dioxolanones or with diphenyl carbonate. These reactions are accelerated by catalysts, especially alkali, tin and titanium compounds (see, for example, plastics manual, vol. 3/1 polycarbonates, Hanser Verlag, Kunststoff, 1992, pp. 118 f.).
- aliphatic polycarbonate homo- and copolymers can be obtained by ring-opening homo- or copolymerization of cyclic carbonates by means of DMC catalysis.
- the invention thus relates to aliphatic polycarbonate homo- and copolymers which are obtained in whole or in part by ring-opening homo- or copolymerization of cyclic carbonates by means of DMC catalysis.
- Suitable cyclic carbonates have the general formulas (I.) or (II.)
- Cyclic carbonates (I) or (II) used with preference are trimethylene glycol carbonate, neopentyl glycol carbonate, 1,4-butanediol carbonate and dimeric carbonates of pentanediol or hexanediol. 6-ring carbonates, in particular neopentyl glycol carbonate, are particularly preferred.
- Suitable DMC catalysts are known in principle and are described in detail in the prior art cited above. Improved, highly active DMC catalysts, which e.g. are described in US-A 5 470 813, EP-A 700 949, EP-A 743 093, EP-A 761 708, WO 97/40086, WO 98/16310 and WO 00/47649. A typical example is the highly active DMC described in EP-A 700 949
- Catalysts which, in addition to a double metal cyanide compound (e.g. zinc hexacyano cobaltate ( ⁇ i)) and an organic complex ligand (e.g. tert-butanol), also contain a polyether with a number average molecular weight greater than 500 g / mol.
- a double metal cyanide compound e.g. zinc hexacyano cobaltate ( ⁇ i)
- an organic complex ligand e.g. tert-butanol
- the DMC-catalyzed ring-opening homo- or copolymerization of the cyclic carbonates is generally carried out at temperatures from 20 to 200 ° C, preferably in the range from 40 to 180 ° C, particularly preferably at temperatures from 80 to 160 ° C.
- the reaction can be carried out at total pressures of 0.001 to 20 bar.
- the polymerization can be carried out in bulk or in an inert organic solvent, e.g. Toluene or THF.
- the amount of solvent is usually 10 to 30% by weight, based on the amount of the polymer to be prepared.
- the catalyst concentration is generally in the range from 0.0005% by weight
- 1% by weight preferably in the range from 0.001% by weight to 0.1% by weight, particularly preferably in the range from 0.001 to 0.05% by weight, based on the amount of the polymer to be prepared.
- the polymerization can be carried out continuously or batchwise, for example in a batch or semi-batch process.
- the DMC-catalyzed ring-opening homo- or copolymerization of the cyclic carbonates is carried out in the presence of one or more starter compounds containing active hydrogen atoms.
- OH-functionalized aliphatic polycarbonate homo- and copolymers can be produced which are suitable as polyol components for the construction of polyurethane systems.
- Compounds with molecular weights of 18 to 10,000 g / mol and 1 to 8 hydroxyl groups are preferably used as starter compounds having active hydrogen atoms.
- Examples are water, ethanol, butanol, ethylene glycol, diethylene glycol, triethylene glycol, 1,2-propylene glycol, 1,4-butanediol, hexamethylene glycol, bisphenol A, trimethylolpropane, glycerol, pentaerythritol, sorbitol, cane sugar, degraded starch, polyether polyols and polyester polyols.
- the DMC-catalyzed ring-opening polymerization of the cyclic carbonates can be as
- Homopolymerization are carried out, optionally in the presence of one or more starter compound (s) having active hydrogen atoms.
- the DMC-catalyzed ring-opening polymerization of the cyclic carbonates can also be carried out as a copolymerization, again optionally in the presence of one or more starter compounds containing active hydrogen atoms. Both statistical copolymerization and block copolymerization are possible.
- the DMC-catalyzed ring-opening polymerization of the cyclic carbonates is carried out in the presence of one or more of any other monomers suitable for the polymerization with DMC catalysts.
- Epoxides in particular ethylene oxide, propylene oxide and butylene oxide and mixtures thereof, oxetanes, cyclic anhydrides such as phthalic anhydride, cyclic esters such as caprolactone and lactides are particularly suitable for statistical copolymerization with cyclic carbonates.
- polycarbonate block copolymers the aliphatic polycarbonate block is obtained according to the invention by means of DMC-catalyzed ring-opening polymerization of cyclic carbonates.
- Preferred block copolymers are poly (ester block carbonate) copolymers and poly (ether block carbonate) copolymers, it being possible for the ester or ether block to be obtained by any process or catalyst.
- a polyether polyol is first prepared in a known manner by DMC-catalyzed polyaddition of epoxides, in particular propylene oxide and / or propylene oxide / ethylene oxide mixtures, to the starter compounds listed above having active hydrogen atoms, and the active compounds
- epoxides in particular propylene oxide and / or propylene oxide / ethylene oxide mixtures
- Polyether polyol containing DMC catalyst is then reacted in a manner according to the invention with the cyclic carbonates with ring opening.
- all or part of the secondary hydroxyl groups of the polyether polyol can be converted into primary hydroxyl groups which are more reactive for the reaction with isocyanate groups.
- Such poly (ether carbonate) polyols are therefore of great interest for use in polyurethanes.
- Example 2 1,000 g / mol) and 2 mg of the DMC catalyst used in Example 1 are introduced under argon and heated to 105 ° C. Subsequently, 20 g of propylene oxide were metered in continuously under normal pressure at 105 ° C. in the course of 3 hours. After the propylene oxide had been metered in, 15.6 g of neopentyl glycol carbonate were added and the mixture was then stirred at 150 ° C. for 1 hour under normal pressure. Then volatile constituents were distilled off at 150 ° C./1 mbar for 1 h and the reaction mixture was then cooled to room temperature.
