Abstract
PURPOSE: To obtain a light transmitting tube having improved impact resistance, ultraviolet light shielding property and durability with reduced diameter and wall thickness of the tube, by incorporating a benzotiazole compound with polymethyl methacrylate.
CONSTITUTION: 0.05W2.0wt%, Preferably 0.25W2.0wt% from the standpoint of the durability, 2-phenyl-benzotriazole compound expressed by the formula [R1 is CH3 or C(CH3)3; R2 is H, CH3 or C(CH3)3; X is H or Cl], e.g. 2-(2'-hydroxy-5'- methyl-phenyl)benzotriazole, is incorporated with polymethyl methacrylate. The process is preferably carried out by adding the compound to a preliminarily polymerized polymethyl methacrylate, and cast polymerizing th resultant mixture. The average polymerization degree of the polymer is ≥7,000.
