    • The present invention provides: a process for producing a high molecular weight thermoplastic resin composition, which can give the high molecular weight thermoplastic resin composition with good reproducibility and stably; and uses of the resultant resin composition. The process for producing a high molecular weight thermoplastic resin composition comprises the step of mixing a thermoplastic resin with pyromellitic dianhydride to carry out a reaction therebetween to convert the thermoplastic resin into a high molecular weight one, and this process is characterized in that the pyromellitic dianhydride has at least one of the following properties in particle form: (1) intrinsically linear or needle-like particle forms; (2) a bulk density of 0.4˜0.9 g/ml; and (3) a rest angle of 50˜70 degrees.

    • A vehicle lamp includes a semiconductor light emitting device arranged to face toward a front of the vehicle lamp, a first optical member disposed in front of the semiconductor light emitting device, and a second optical member disposed in front of the first optical member. The first optical member comprises a front surface and a back surface. The front surface is configured to internally reflect light from the semiconductor light emitting device toward the back surface. The back surface is configured to internally reflect the light reflected by the front surface back toward the front surface such that the light exits the first optical member from the front surface. The second optical member is disposed directly in front of the front surface of the first optical member and diffuses the light from the first optical member to form a light distribution pattern.
