A halogen-free radiation curable flame retardant composition that comprises an end-capped oligomer of a phosphonate polyol and a polyisocyanate and an organic monomer.

Halogen-free radiation curable flame retardant compositions

Photocurable liquid coating compositions adapted to provide primary coatings for optical glass fibers are disclosed. These compositions comprise an acrylate-terminated polyurethane, an acrylate of an unsubstituted or C.sub.1 -C.sub.10 alkyl substituted phenol that is alkoxylated with a C.sub.2 -C.sub.4 alkylene oxide and at least one alkylacrylate having a T.sub.g below about -45.degree. C. Films produced from these ultraviolet light curable compositions are flexible and possess good water resistance and good wet adhesion.

Primary coatings for optical glass fibers including polyether acrylates

Photocurable liquid coating compositions adapted to provide primary coatings for optical glass fibers are disclosed. These compositions comprise polycarbonate-based acrylate-terminated polyurethane, an acrylate of an unsubstituted or C.sub.1 -C.sub.10 alkyl substituted phenol that is alkoxylated with a C.sub.2 -C.sub.4 alkylene oxide and at least one alkylacrylate having a T.sub.g below about -45.degree. C. Films produced from these ultraviolet light curable compositions are flexible and possess good water resistance and good wet adhesion.

Primary coatings for optical glass fibers including

Substantially hydroxy free, liquid, ultraviolet-curable compositions comprise cationically polymerizable ethylenically unsaturated material including a vinyl ether-terminated polyurethane which is the reaction product of isocyanate-reactive material including a monohydric vinyl ether and a diisocyanate having the formula: ##STR1## in which R is an alkylene group containing from 1-10 carbon atoms, this polyurethane having a number average molecular weight in the range of from 2000 to 6000, and a curing effective amount of a cationic photoinitiator which initiates a cationic cure when exposed to ultraviolet light, but less than 1% thereof based on the weight of the unsaturated material subjected to polymerization. These coatings are applied with a thickness of from 1 to 10 mils and cured with ultraviolet light, and they are particularly adapted to provide primary and single coatings for optical glass fiber.

Ultraviolet-curable cationic vinyl ether polyurethane coating

An hydroxy-functional polyurethane reaction product is disclosed which enables the provision of thermosetting solution coating compositions which cure at low temperature to form flexible coatings. These polyurethanes are provided by the reaction of an organic diisocyanate with a stoichiometric excess of an essentially linear hydroxy-functional polyester which is the polyesterification reaction product of C.sub.4 -C.sub.10 aliphatic dicarboxylic acid or anhydride thereof with a stoichiometric excess of C.sub.3 -C.sub.8 aliphatic diol providing an alcohol/acid molar ratio of 3/2 to 6/5. The reaction is substantially complete as indicated by an acid number less than 10, and the diisocyanate is used in an amount providing an NCO/OH ratio of from 2/3 to 12/13. The thermosetting solution coating composition is provided by an organic solvent having dissolved therein from 5-50% of total resin solids of a curing agent reactive with hydroxy groups together with the polyurethane which has been described. The preferred curing agent is a partially methylolated melamine which contains from about 5 mol percent to about 40 mol percent of the methylol group.

Low temperature-curing polyester urethane systems

A process is disclosed in which polyalkoxy amino silane adhesion promoters are incorporated into isocyanate-functional polyurethane resins formed by the reaction of a stoichiometric excess of organic polyisocyanate with an hydroxy-functional resin without producing cloudy and/or unstable resin solutions. In this process, the hydroxy-functional resin is prereacted with the alkoxy functionality of the amino silane in a reaction which liberates alcohol, and then a stoichiometric excess of the organic polyisocyanate is added to cause the isocyanate groups of the polyisocyanate to react with both the hydroxy groups and the amino hydrogen atoms present.

Preparation of isocyanate-terminated polyurethanes containing amino

Hydrocarbon gels formed from liquid hydrocarbons with pseudo double salts of alkyl acid orthophosphoric acids as gelling agents are made stable to the presence of excess caustic materials by the addition of an anhydride of a C.sub.2 - C.sub.10 carboxylic acid or dicarboxylic acid.

Stabilized hydrocarbon gels and a method for their preparation

Gelled hydrocarbon compositions comprising a liquid hydrocarbon, a partial aluminum salt of an alkyl acid orthophosphate and a neutralizing amount of a polyamine which retain gel character in the presence of epoxy resins and aromatic diamines and a method for their preparation.

Polyamine salts of aluminum alkyl orthophosphates

The minimum pour temperature of a fatty acid, analogous to the ASTM pour point of a hydrocarbon oil, may be lowered by 70.degree.F. and more by the method of this invention, which comprises mixing therewith from 5 to about 50 parts by weight of a C.sub.2 -C.sub.18 acyclic monoamine or diamine. The method of this invention is applicable to a wide variety of fatty acids and mixtures.
