Abstract
THERE IS PROVIDED A RESIN COMPOSITION FOR OPTICAL FIBER LOOSE TUBES WHICH ENABLES THE PRODUCTION OF BOTH COLORED LOOSE TUBES AND NON-COLORED LOOSE TUBES UNDER THE SAME EXTRUSION MOLDING CONDITIONS, EVEN THE PRODUCTION OF OPTICAL FIBER LOOSE TUBES OF THE SAME QUALITY, PARTICULARLY THE SAME QUALITY IN TERMS OF EXTRA LENGTH AND POST-SHRINKAGE, AND HAS EXCELLENT HYDROLYSIS RESISTANCE AS WELL AS AN OPTICAL FIBER LOOSE TUBE. THE RESIN COMPOSITION IS OBTAINED BY BLENDING A MASTER BATCH (A) PRODUCED BY MELT KNEADING 100 PARTS BY WEIGHT OF (A) POLYBUTYLENE TEREPHTHALATE AND 0.1 TO 5 PARTS BY WEIGHT OF (B) A CRYSTAL NUCLEATING AGENT WITH POLYBUTYLENE TEREPHTHALATE (B) IN AN AMOUNT 10 TO 100 TIMES THE WEIGHT OF THE MASTER BATCH. THE AMOUNT OF THE CRYSTAL NUCLEATING AGENT IS 0.01 TO 0.5 WT% BASED ON THE TOTAL AMOUNT OF THE RESIN COMPOSITION AND THE POLYBUTYLENE TEREPHTHALATE (B) HAS A TERMINAL CARBOXYL GROUP CONCENTRATION OF 30 EQ/TON OR LESS AND AN INTRINSIC VISCOSITY OF 1.0 TO 1.2.
