Abstract
Solventless polymeric compositions suitable for coatings and moldings are formed by the addition reaction product of a first component comprising mono, di or polyamines, or an adduct of mono, di or polyamines with mono, di or polyfunctional acrylates and/or epoxides and a second component comprising mono, di or polyacrylates or mixtures with mono, di or polyepoxides.
Claims13
A copolymer comprising the addition reaction product of:
- a first solventless component comprising an adduct of a mono, di or polyamine with a mono, di or polyfunctional acrylate or epoxide or mixtures thereof;
- and
- a second, solventless component comprising a di or polyacrylate or mixture thereof, or a mixture of a di or polyacrylate and a glycidyl ester of acrylic acid or methacrylic acid.
A copolymer comprising the addition reaction product of
- a first component comprising a mono, di or polyamine, hydrazine, or an amino-hydrazine terminated derivative, or a mixture thereof with a mono, di or polyfunctional acrylate and
- a second component comprising a di or polyacrylate
- wherein the first and second components are mixed together in proportions such that the number of acrylic linkages are in excess of the aminic hydrogens so as to form a photoprepoymer which can be further polymerized by ultraviolet light or an electron beam.
