摘要
(WO2015189793) A method for the synthesis of acrylic resin by means of a radical reaction comprises: a loading and activation step that provides mixing and gradual heating of methyl methacrylate, one or more thermal initiators such as azobisisobutyronitrile and one or more mercaptan chain transfer agents in a discontinuous production reactor, in order to obtain a homogeneous mixture, a reaction step that provides incubation of the reaction, including stopping the mixing and maintaining the heat of the mixture and completion of the reaction with low-rpm regimen stirring of the mixture, and a cooling step that provides cooling and stirring of the homogeneous mixture to obtain a casting acrylic resin.

(WO2015189793) 1. Method for the synthesis of acrylic liquid resin by means of a radical reaction, said method comprising: - a loading and activation step that provides: i) supplying in a single load, in a discontinuous production reactor, methyl methacrylate, one or more thermal initiators of the azobisisobutyronitrile type and one or more mercaptan chain transfer agents, and mixing and gradual heating of the methyl methacrylate, of the one or more thermal initiators such as azobisisobutyronitrile and the one or more mercaptan chain transfer agents in the discontinuous production reactor, in order to obtain a homogeneous mixture, in which the gradual heating provides to heat and keep the mixture at a temperature between about 58deg.C and about 65deg.C; - a reaction step that provides: ii) incubation of the reaction, including stopping the mixing at a temperature between about 55deg.C and about 60deg.C and maintaining the heat of the mixture during which the temperature is maintained at a value constantly comprised between 55deg.C and 60deg.C; iii) completion of the reaction with low-rpm regimen stirring of the mixture comprised between 55 and 90 rpm; - a cooling step that provides: iv) cooling and stirring of the homogeneous mixture to obtain a casting acrylic liquid resin.
