Optical fiber coating compositions with acrylic polymers

A compound of formula (I), formula (II), or a combination thereof, and salts thereof is described. Each A may be independently an optionally substituted conjugated species or an optionally substituted aromatic species. Each R may be independently an optionally substituted C-Clinear alkyl chain, an optionally substituted branched alkyl chain, an optionally substituted alkyl chain containing heteroatoms, substituted alkyl chains, or H. Each Rmay be independently an optionally substituted C-Clinear alkyl chain, an optionally substituted branched alkyl chain, an optionally substituted alkyl chain containing heteroatoms, substituted alkyl chains, H, or part of a cyclic boronate ester with an other R. Each n may be independently less than or equal to 3 and greater than or equal to 1. Each x may be independently less than or equal to 3.

Boron ester fused thiophene monomers

A method of synthesizing urethane-free polyfunctional acrylate compounds. The method includes reaction of a polyol with acrylic acid in the presence of an inhibitor. A catalyst may also be present. The catalyst may be an acid and the inhibitor may be a substituted phenol compound. Excess acid may be removed by adding a salt and excess water may be removed by adding a drying agent. The reaction converts alcohol groups of the polyol to acrylate groups to provide a radiation-curable polyfunctional acrylate compound. The reaction is applicable to polyols generally and provides a scalable high yield process for forming urethane-free polyfunctional acrylates over a wide range of molecular weights. Coatings made from the acrylate products exhibit modulus and tensile strength characteristics favorable for primary fiber coatings.
