Procedure for Toughening unsaturated Polyester Resins.

摘要

Process for the production of unsaturated Polyester Resins Accelerated.Is to react - 75 30 parts by weight of ethylenically unsaturated Polyester Ba, BB -, 70 - 25 parts by weight of monomers with the previous copolimerizables with 1.0 - 10 weight, referred to the unsaturated Polyester resin, Accelerator of formula (i) and other Auxiliary agents under dist Ribucion Homogeneous and thus obtained the Mass Hardens where R1 and R2 are a remnant HydrocarbonSaturated or unsaturated with C 1 to 18; R3 and R4 are a remaining alkyl C 1 to 4 and others.
