Embodiment

[0080] All tests are performed according to IPC TM650.

[0081] The IPC test method is the following electrical laminate industry standard (The Institute For Interconnection and Packaging Electronic Circuits, 3451 Church Street, Evanston, Illinois 60203):

[0082] method

[0083] A) Preparation of Tripropargylboroxine (Compound (I))

[0084] A mixture of 3 moles of propargyl alcohol and 1 mole of trimethoxyboroxine is heated to a temperature of 120-150° C. until distillation of methanol ceases.

[0085] Boiling point: 85-88°C (10mm Hg pressure)

[0086] B) Laminates

[0087] Fiberglass laminate composites were prepared by a solvent impregnation method. The components are dissolved in solvent and then coated onto 7628 fabric, an industry standard fiberglass fabric (Procher SA 7628 with silane or polyimide) defined by the glass strip, thickness and weight of the glass fabric. amine finish). The solvent is then evaporated and the composition is B-staged. The prep...

Abstract

The present invention relates to boroxine-derived compounds, such as tripropargylboroxines, their preparation, and their use as flame retardants in polymer resins, especially thermosetting polymer resins.

Description

technical field [0001] The present invention relates to compounds derived from boroxines and their use as flame retardants in polymer resins, especially thermosetting polymer resins. Background technique [0002] The flame retardancy of polymer resins, especially thermosetting polymer resins, such as for example epoxy resins, benzoxazine resins, cyanate resins or polyimide (addition and thermoplastic) resins, remains important for many applications. insufficient. In order to make the polymer resin flame retardant, it is necessary to add compounds or fillers containing bromine, phosphorus or chlorine. Commonly offered solutions for rendering compositions flame retardant are based on inert fillers or halogen-containing compounds or other additives, which in principle have one or more of the following disadvantages: [0003] - They are inert materials that do not react with the system and thus may cause problems in processing. [0004] - They reduce the thermal behavior of t...
