摘要:
CYCLIC BORATE OF POLYMERIC ALKANOLAMINE FORMED BY REACTING A BORYLATING AGENT WITH A POLYMERIC ALKANOLAMINE. THE CYCLIC BORATE IS USED AS AN ADDITIVE IN ORGANIC SUBSTANCES TO INHIBIT DETERIORATION DUE TO OXIDATION, WEATHERING, HEAT OR OTHER UNDESIRED REACTIONS.
摘要:
Flame retardant polymers of benzene phosphorus oxydichloride, 4,4'-thiodiphenol and POCl.sub.3 are disclosed which are preferably formed by reacting these monomers in an inert organic solvent at ambient temperature in the presence of an amine acid acceptor.

NOVEL MIXED ARYL BORATES OF THE GENERAL FORMULA BOX(OAR)Y, WHEREIN X IS GREATER THAN O BUT LESS THAN 1 AND Y IS LESS THAN 1, WHICH MIXTURE CONTAINS OPEN CHAIN ARYL BORATES OF THE FORMULA:
(AR-O-)2-B-(O-B(-O-AR))(N=>0)-O-B(-O-AR)2
WHICH MIXED ARYL BORATES ARE MADE BY REACTING LESS THAN 3 MOLS OF A PHENOLIC COMPOUND PER BORON ATOM WITH BORIC ACID OR BORIC OXIDE AT ELEVATED TEMPERATURES AND FOR EXTENDED PERIODS OF TIME SUFFICIENT TO CONDENSE THE BORON COMPOUND AND THE PHENOLIC COMPOUND AND CAUSE WATER AS WELL AS PHENOLIC COMPOUND TO BE CONDENSED OUT OF THE REACTION AND REMOVED THEREFROM. THESE MIXED ARYL BORATES ARE REACTABLE WITH FORMALDEHYDE OR FORMALDEHYDE YIELDING MATERIALS TO PRODUCE THERMO-SETTING RESINS OF THE PHENOL-ALDEHYDE TYPE CONTAINING BORON THEREIN.
