ABSTRACT:

BACKGROUND OF THE INVENTION
Field Of The Invention
This invention relates to polymers made from triazine derivatives for producing intermediates and molded materials characterized by improved toughness, high flame resistance and strength, and to methods of their production.
Polymers made from triazine derivatives such as melamine formaldehyde resins [Ullmanns Encyclopedia of Industrial Chemistry (1997), Vol. A2, pp. 130-131], benzoguanamine formaldehyde resins [Duroplaste, Kunststoff-Handbuch Bd. 10, pp. 994-997, Carl Hanser-Verlag München 1999], polytriazine ethers or polyamino triazine [Bjuller, K., Teplo-i Termostoikie Polimery, pp. 585—585, Moskva, Khimia 1984] are known. A disadvantage of polymers from triazine derivatives is the low toughness of intermediates and molded materials produced from them.
Also known are melamine propylene oxide block copolymers (DE 21 18 888) and block copolymers from N.N′-hydroxyethyl melamines or N.N′-hydroxyaryl melamines with ethylene oxide and propylene oxide (U.S. Pat. No. 4,358,304). These block copolymers share the disadvantage that products made from them, despite their good toughness, will result in intermediates and molded materials of reduced flame resistance and strength due the length of the polyalkylene oxide sequences in the block copolymer and the occurrence of unbound polyalkylene oxide as a byproduct during production.
SUMMARY OF THE INVENTION
It is the problem of this invention to provide polymers made from triazine derivatives for producing intermediates and molded materials characterized by improved toughness, high flame resistance and strength, as well as methods of their production.
This problem is solved according to the invention based on
A) 80 to 95 percent by weight of triazine derivative mixtures consisting of
A1) 20 to 70 percent by weight of triazine derivatives with hydroxyalkyl amino groups of the formula
