Title:
POLYETHYLENE-2,6-NAPHTHALATE COMPOSITION WITH EXCELLENT BLOW MOLDABILITY, AND MOLDED PRODUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/125846
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a high crystallinity polyethylene-2,6-naphthalate composition, the blow moldability of which is dramatically improved by achieving a high PEN molecular mass, and the molded product of said composition exhibits excellent hue, transparency and weathering resistance. The aforementioned problem can be solved by means of a polyethylene-2,6-naphthalate composition containing a specific phosphonic acid compound which is a phosphorous compound, a cobalt element derived from a cobalt compound, a manganese element derived from a manganese compound, and an antimony element derived from an antimony compound, wherein the content of the aforementioned elements simultaneously satisfy the following expressions (1) to (4): expression (1) is 10 ≤ Co ≤ 30 mmol%; expression (2) is 0.50 ≤ P/Mn ≤ 1.28; expression (3) is 10 ≤ Sb ≤ 25 mmol%; and expression (4) is 0.60 ≤ IV ≤ 1.50 dL/g.
