Abstract

A method of reducing the flow viscosity of a polyacrylate composition, which comprises addinga) to a polyacrylate, a polyacrylate copolymer, a polyacrylate mixture or a mixture of polyacrylates and polyacrylate copolymers having an average molecular weight of more than 500000 g/molb) a polyacrylate, a polyacrylate copolymer, a polyacrylate mixture or a mixture of polyacrylates and polyacrylate copolymers having an average molecular weight of less than 500000 g/mol,component (b) possessing functional groups crosslinkable by UV irradiation.
