摘要
The present invention relates to a production method of a plastic optical fiber which comprises the steps of heat drawing an undrawn plastic optical fiber obtained by melt spinning and annealing the drawn fiber at a circumferential velocity ratio between the front and rear rollers (circumferential velocity of a rear roller / circumferential velocity of a front roller) of 0.5 to 1.2 under heating conditions which satisfy 4 /= y /= -1.5x + 330 and (Tgc - 5) DEG C /= x /= (Tgc + 110) DEG C ÄTgc: a glass transition temperature of a core, x: an annealing temperature ( DEG C), and y: an annealing time (seconds)Ü. According to the present invention, a plastic optical fiber having a small thermal shrinkage ratio and excellent heat resistance can be provided. IMAGE
