In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Eutectic solidification of the quasi binary system of isotactic polypropylene and pentaerythrityl tetrabromide, published in 1977, which mentions a compound: 3229-00-3, mainly applied to eutectic solidification polypropylene pentaerythrityl bromide, Product Details of 3229-00-3.
The title eutectic solidification was studied to gain some understanding of the simultaneous crystallization of a polymer and a diluent with a metal-like character. Pentaerythrityl tetrabromide (I) [3229-00-3] had a melting range of 157-9°, appropriate for the occurrence of a eutectic point. Despite the fact that the value of α = 6 of I was rather high, in polymer solutions I produced dendrites upon solidification, typical of metallic behavior, and I was classified as pseudodendritic. Considering the metal-like habit of both components, it was expected that the eutectic solidification process would proceed in a cooperative way, forming regular structures which should depend on the growth rate. In controlled solidification of the I-isotactic polypropylene (II) [25085-53-4] eutectic, coupled growth of the I and II mols. was observed at growth rates <3 mm/h. The formed eutectic microstructure consisted of I rods dispersed in a II matrix. The lateral dimension of these rods depended on the rate of solidification and ranged from 0.3 to 1.0 μm. At growth rates <3 mm/h, uncoupled growth of I and II was observed, producing a structure of randomly mixed II spherulites and I crystals. In the solidification of off-eutectic solutions with an excess of I, a remarkable nucleating effect of the primary I crystals was found. This indicated the importance of eutectics in polymeric systems, which could be applied in dispersing crystalline additives such as nucleating agents or in the in situ production of polymer composites. Also, solidification of eutectic polymer-diluent systems provided a method for producing porous materials by removal of the small mol. compound, where the lateral dimensions of the pores depended on the growth rate. This literature about this compound(3229-00-3)Product Details of 3229-00-3has given us a lot of inspiration, and I hope that the research on this compound(Pentaerythrityltetrabromide) can be further advanced. Maybe we can get more compounds in a similar way.
