    摘要： A resin film with at least 50 wt % of at least one polymerisable vinyl ester prepolymer having at least two carbon-carbon unsaturated functional groups and a curing system, the prepolymer in a concentration of at least 10 wt %, based on the weight of the polymerisable resin, and has the structure R1n-R2-R1′m, wherein R1 and R1′ are the same or different, n and m are each at least one and may be the same or different, and each of R1 and R1′ includes a carbon-carbon unsaturation at a free end thereof remote from R2, and includes a residue of an epoxy resin, and wherein R2 is a polyfunctional chain extending linker between R1 and R1′, and is derived from a polyfunctional carboxylic acid having the structure R-Fnx, where Fn is a carboxylic acid functional group, x is at least 2, and R comprises an organic moiety having aliphatic, araliphatic, cycloaliphatic, heterocyclic and/or aromatic groups, containing any type and/or combination of saturated, unsaturated and/or aromatic carbon bonds, and wherein R may be unsubstituted or substituted by functional groups and/or heteroatoms.

    摘要： Viscosifiers, especially terminated polymers that have functional terminal groups, the polymers being pre-extended by polyols and being reacted to give polymers that are terminated by other functional groups, are produced. The viscosifiers have a low content in educts or educt descendants that deteriorate the properties of compositions. The formation of high-molecular addition products is considerably reduced or even excluded so that the products obtained have low viscosity and good storage stability. The epoxy-terminated polymer of formula (I) is especially preferred.
