Title:
NON-CRYSTAL-FORMING OLIGOMERS FOR USE IN RADIATION-CURABLE FIBER OPTIC COATINGS
Document Type and Number:
WIPO Patent Application WO2002053509
Kind Code:
A3
Abstract:
A radiation-curable coating composition for an optical fiber comprising a reactive functionality-terminated urethane oligomer, wherein said oligomer comprises the reaction product of (i) a semi-crystalline polyol, and (ii) a non-crystalline polyol in the mole ratio of semi-crystalline polyol to non-crystalline polyol of between about 10:1 and 1:10, (iii) at least one isocyanate, and (iv) an endcapping compound capable of supplying the reactive functionality terminus.
