Title: Production of improved phenolic resin
Inventor: KUNO JUNICHI
IPC: B32B27/42
Filed: 1985-08-23
Abstract: PURPOSE:To obtain a phenolic resin having excellent physical properties and high flame retardancy, by adding an oxyalkylene tris(hydroxypropyl)phosphine oxide to or reacting it with the reaction mixture in the production of a phenolic resin. CONSTITUTION:In the production of a phenolic resin, a phosphine oxide derivative obtained by adding at least one compound selected from among ethylene oxide, propylene oxide and styrene oxide to tris(hydroxypropyl)phosphine oxide is added to and/or reacted with the reaction mixture. The tris(hydroxypropyl) phosphine oxide used is obtained by reacting allyl alcohol with phosphine and oxidizing the product. Although the amount of the alkylene oxide added may be suitably changed, it must be added in an at least certain amount when improvement in interlayer adhesion and punching quality is aimed at. When this amount is excessively large, the phosphorus content is decreased and the flame retardancy is decreased. Therefore, a desirable amount of addition is 1-10mol per mol of phosphine oxide.
