摘要： In manufacturing a thermoplastic copolymer by copolymerizing an aromatic vinyl monomer, a vinyl cyanide monomer, and, when necessary, a vinyl monomer (a) copolymerizable with the above two monomers, at least a part or all of the vinyl cyanide monomer is put in a reactor and copolymerizing reaction is started, and a weight of an unreacted portion of the aromatic vinyl monomer is caused to become greater than a weight of an unreacted portion of the vinyl cyanide monomer when all the monomer components are put in the reactor. By doing so, a ratio of the vinyl cyanide monomer in a structural unit of a thermoplastic copolymer produced at latter stages of the copolymerizing reaction is lowered. Thus, the present invention is capable of providing a thermoplastic copolymer which has excellent physical properties such as good heat resistance and good mechanical strength and is hard to discolor, as well as a manufacturing method thereof.

摘要： This invention provides a maleimide-based copolymer in which, because its molecular weight-retention ratio at high temperature is high, deterioration of physical properties by heating is little. Also, this invention provides a process wherein a maleimide-based copolymer is arranged so as not to heat more than necessity and thereby a maleimide-based copolymer containing only a small amount of residual volatile components is efficiently obtained without deterioration of physical properties. The maleimide-based copolymer is such as having a glass transition temperature of 170.degree. C. or higher, a weight-average molecular weight of 100,000 to 500,000, and a molecular weight-retention ratio of 90% or more when heated at 280.degree. C. for 10 minutes. When this copolymer is produced, volatile components are separated by supplying a polymer composition containing said copolymer and volatile components to a vent type screw extruder and operating this extruder under condition of a screw rotation number of 50 to 150 rpm.
