Patent ID: 7385014

Claim:
A method of using ethylenically unsaturated isocyanate derivatives of the general formula (1): comprising the step of selecting X from the group consisting of formulae X 1 , X 2 , X 3 , X 4 : where A is a linear or branched alkylene group with 4 to 6 carbon atoms or a group selected from a group consisting of formulae A 1 , A 2 , A 3 , A 4 , A 5 , A 6 : (in which R independently of one another represent hydrogen atoms or methyl groups, m represents a whole number with values of 0 or 1 and n represents whole number with values of 0 to 4), R 1 represents a hydrogen atom or a methyl group, and R 2 represents a linear or branched alkylene group with 1 to 6 carbon atoms as agents for covalently bonding water, monohydric or multihydric alcohols, glycerol, polyethtylene glycol with weight average molecular weights ranging from 62 to 750, polypropylene glycol with weight average molecular weights ranging from 76 to 3500, and phthalate plasticizers in dowel and/or fastening compositions based on ethylenically unsaturated monomers, oligomers and polymers as resin components and organic peroxides as curing agent, wherein the ethylenically unsaturated isocyanate derivatives of the general formula (I) together with the resin component, are in a first component of a two-component fastening mortar and the curing agent is in a separate second component.
