摘要： The present invention provides a production process for a transparent heat-resistant resin, and further, a transparent heat-resistant resin and uses therefor, wherein the production process involves high dealcoholation conversion and a low content of residual volatiles in the resultant resin, and therefore can prevent foam or silver streak from occurring in the molded product, and further, facilitates melt-molding such as injection molding, and is fit for industrial production, and involves good efficiency. The production process for a transparent heat-resistant resin comprises the step of running a dealcoholation reaction of a polymer having a hydroxyl group and an ester group in its molecular chain to introduce a lactone ring structure into the polymer to obtain a transparent resin having the heat resistance, and is characterized in that the dealcoholation reaction is run in the presence of a solvent, and further characterized by further comprising a devolatilization step which is carried out jointly with the dealcoholation reaction.

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： N-Cyclohexylmaleimide having a cyclohexylaminosuccinic anhydride content of 0.001 to 1 wt. % is used as the main raw material for the production of heat-resistant resins. The resins are produced by a process of copolymerizing the above material with at least one monomer copolymerizable therewith which is characterized by the use of a monomer having a low yellowness, the addition of a compound which can inhibit the evaporation of the non-radical compounds contained in the monomer through reactions, the addition of an antioxidant, the use of a solvent containing alcohol, or the presence of a non-radical-polymerizable acid anhydride or carboxylic acid. The heat-resistant resins produced by the use of the above raw material or the above process are excellent in transparency, i.e., less discolorable, even when an increased amount of N-cyclohexylmaleimide is used for the purpose of imparting more excellent heat resistance. Accordingly, the heat-resistant resins can be suitably used in the fields necessitating both a low discolorability and a high heat resistance.

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.
