    摘要： In the invention, a polyester resin comprising dicarboxylic acid constitutional units and diol constitutional units wherein 5 to 60 mol % of the diol constitutional units has a cyclic acetal skeleton is produced by a process comprising an oligomerization step and a polymerization step. In the oligomerization step, an ester having a limited acid value is transesterified with a diol having a cyclic acetal skeleton in the presence of a basic compound to obtain an oligomer. The oligomer is then polymerized in the subsequent polymerization step to increase the molecular weight.

    摘要： Provided is a thermoplastic resin laminate including: a thermoplastic transparent resin (A) layer; a thermoplastic resin (B) layer formed of a methyl methacrylate-styrene copolymer and/or an acrylonitrile-styrene copolymer; and a thermoplastic resin (C) layer formed of a polycarbonate-based resin, the (B) layer being laminated on one surface, or each of both surfaces, of the (C) layer, and the (A) layer being laminated on the surface of the (B) layer, in which the thermoplastic transparent resin (A) includes a vinyl copolymer resin containing a (meth)acrylate constituent unit (a) and an aliphatic vinyl constituent unit (b) each having a specific structure at a molar ratio between the (meth)acrylate constituent unit (a) and the aliphatic vinyl constituent unit (b) of 15:85 to 85:15. The thermoplastic resin laminate has such characteristics as to be excellent in, for example, weather resistance against high-temperature, high-humidity environments, abrasion resistance, and interlayer adhesion, and is used, as a transparent substrate material or a transparent protective material, for an optical product, and in particular, portable display devices such as portable phone terminals, portable electronic game devices, and PDA's.
