Abstract
Official abstract text for this publication.
Epoxy resin compositions comprising a) epoxy resins and b) at least one 2-oxo-[1,3]dioxolane derivative of the formula I in which one or two of the radicals R1 to R4 are an electron-withdrawing organic group having 1 to 20 C atoms or an electron-withdrawing heteroatom, and the remaining radicals R1 to R4 are independently of one another an H atom or a hydrocarbon group having 1 to 20 C atoms.
First claim
Opening claim text (preview).
The invention claimed is: 1. An epoxy resin composition, comprising: a) an epoxy resin; and b) at least one 2-oxo-[1,3]dioxolane compound selected from the group consisting of a 2-oxo-[1,3]dioxolane-4-carboxylic ester of formula (Ia) and a 2-oxo-[1,3]dioxolane-4,5-carboxylic diester of formula (Ib): wherein, in formulae (Ia) and (Ib), R 5 is a C1 to C10 alkyl group.…
