摘要
Unsaturated polyester resins having an acid number of from 0 to 50 and a hydroxyl number of from 10 to 150 which are composed of 0.6 to 0.8 moles of groups derived from maleic and/or fumaric acid, 0.2 to 0.4 moles of groups derived from norbornene dicarboxylic acid, 0.6 to 0.8 moles of groups derived from ethylene and/or propylene glycol, 0.2 to 0.4 moles of groups derived from diethylene glycol, 0.1 to 0.2 moles of groups derived from benzylalcohol and/or benzoic acid and 0 to 0.2 moles of groups derived from other alcohols, a process for their manufacture by a solvent-free or azeotropic esterification of said monomers and compositions which can be cured under influence of UV radiation, containing from 40 to 80 parts by weight of said polyester resins, from 20 to 60 parts by weight of styrene from 0.5 to 5 parts by weight of at least one photoinitiator and optionally known auxiliary agents and additives.
