Good thermal stability and self-extinguishing behavior was observed with the cured polybenzoxazine resins. Second, furan-containing benzoxazine monomers, P-FBz, BPA-FBz, and 4FP-FBz were prepared using furfurylamine as a raw material. Formation of furfurylamine Mannich bridge networks in the polymerizations of P-FBz and BPA-FBz increased the cross-linking densities and thermal stability of the resulting polybenzoxazines. P-FBz and BPA-FBz- based polymers also exhibited high glass transition temperatures above 300℃, high char yields, and low flammability with a limited oxygen index value of 31. The dielectric (Dk3.21–3.39) and mechanical properties (high storage modulus of 3.0–3.9 GPa and low coefficient of thermal expansion of 37.7– 45.4 ppm) of the P-FBz and BPA-FBz-based polymers were superior or comparable to other polybenzoxazines. 4FP-FBz used for polybenzo- xazine modification by means of formation of benzoxazine hybridation with P-FBz.

Flame retardants may interrupt or change the decomposition process in several ways:(1)they may melt at relatively low temperatures and resolidify in the form of a foam, which serves as a barrier to heat transfer from the flame to the substrate;(2) they may be converted upon heating into acids or bases, which catalyze the decomposition of the substrate at lower temperatures than are required for the formation of volatile combustibles;(3 ) they may decompose orsublime upon heating to release large amounts of nonflammable vapors which exclude oxygen from the flame; or (4) they may react with chemicakl species within the flame to stop the combustion reaction.
阻燃剂可以从几个方面干涉或改变织物的分解过程:(1)阻燃剂在相对较低的温度时会熔化,然后重新固化成泡沫状,这样就形成了一个屏障,阻止了从火焰向织物的热传递。(2)阻燃剂受热时会分解成酸或碱,这些酸或碱在低于可生成挥发性可燃物的温度下可以催化织物的分解。(3)阻燃剂在受热时会分解或升华,同时释放出大量不可燃气体,这就阻止了氧气对火焰的供应。(4)阻燃剂可以与火焰中的化学物质起反应,使燃烧反应终止。

Combined crystallization kinetics analysis obtained via rheometry and morphological observation of crystals growth performed on POM, two different mechanisms of shear-enhanced crystallization for PP/ grafted MWCNTs composites were suggested:(1) at low temperature, strong heterogeneous nucleation plays a dominant role on the. crystallization behavior, which would be saturated at a higher filler content, and the effect of shear-enhanced crystallization was weak;(2) at high temperature, the effect of heterogeneous nucleation was substantially depressed, and the crystallization of the composite was obviously accelerated by pre-shear and the thread-like crystallites were generated earlier than the spherulites.
