Definitions
- the invention relates to a process for the preparation of double bond-containing polyalkylene oxides with a high molecular weight with a narrow molecular weight distribution and a low glass transition temperature, and to the polyalkylene oxides obtainable by this process.
- Amorphous, high molecular weight polyalkylene oxides in particular (co) polymers containing propylene oxide and / or epichlorohydrin, belong to elastomers due to their high chain flexibility and show elastic behavior even at very low temperatures.
- Rubber-like copolymers of propylene oxide and allyl glycidyl ether have properties which are very similar to those of natural rubbers, but show better aging behavior even at elevated temperatures, as well as better weather stability and ozone resistance.
- they can be vulcanized by reaction with sulfur or in the presence of vinyl monomers such as e.g. Styrene, acrylonitrile and (meth) acrylates, and radical formers such as e.g. Peroxides or percarboxylic acid or percarbonic acid esters are grafted.
- polyalkylene oxides by ring-opening anionically, for example using KOH, or cationically, for example using BF 3 -Et 2 O, induced (co) polymerization of
- Epoxides only provides low molecular weight products (see e.g. DABerta, EJ Vandenberg in Handbook of Elastomers, New Development and Technology, Chap. 19, pp. 643-659, A.K.Bowowmick and HLStephens Eds., Marcel Dekker, New York, 1988).
- particularly desirable are polyalkylene oxides with a low glass transition temperature and high molecular weight which, owing to a simultaneous narrow molar mass distribution, have a lower processing viscosity.
- a variety of coordination catalysts are known for making high molecular weight, rubbery polyalkylene ethers (see e.g. F.E. Bailey and J.V. Koleske in Polyoxyalkylenes, Ulimann's Encyclopedia of Industrial Chemistry, Vol. A21, p.p. 579-589, VCH Publishers, 1992).
- Most catalyst systems use special complexes made from hydrolysis products of Al, Zn or Mg (metal oxanes, see e.g. E.J Vandenberg, J. Polym. Sei., Vol. 47, pp.486-489, 1960).
- the object of the present invention was therefore to produce rubber-like polyalkylene oxides with a high molecular weight and a narrow molar mass distribution which have a low glass transition temperature. Furthermore, high conversions should be achieved in their manufacture using small amounts of catalyst, so that no cleaning steps are required.
- the invention thus relates to a process for the preparation of double bond-containing polyalkylene oxides with a number average molecular weight of

- the catalyst can be preactivated before the polymerization so that the induction period of several minutes to a few hours, which is typical in a batch process, does not occur and the heat of reaction can be controlled by the monomer metering and removed via the solvent, which increases the process reliability. In such cases, work can also be carried out under adiabatic conditions.
