Hartwig, K. Koschek, and A. Luhring Abstract

2-diols the protons required to progress the polymerization can be fixed within five-membered rings. The polymerization rate is decelerated in the presence of such polyols, therefore. The formed structures have some similarity with crown-ethers complexing a proton. And it is therefore not surprising that crown-ethers inhibit the cationic polymerisation very efficiently. On the other hand no retardation of the reaction rate is observed if 1,4-diol based polyethers are used to modify the properties of the materials.

Analogous work for the photochemically induced polymerization of epoxides was published by Yagci and Schnabel [7], who showed that a kind of copolymerization takes place between the diepoxide and the alcohol via a chain-transfer reaction. If a diepoxide is polymerized with a diol or triol, the system becomes crosslinked, whereas the reaction with a monoalcohol leads to dead ends in the polymer network [8]. Crivello et al. [9] found that the rate of the photochemically induced polymerization of 3,4-epoxycyclohexylmethyl-3, 4 -epoxycyclohexane car-boxylate increases if ethylene glycol or 1,4-butanediol is added. At the same time the conversion of epoxy groups increases within the first 3 min of UV irra-
