In the structure of the title compound, [Fe(C(5)H(5))(C(14)H(10)N)], the unsubstituted cyclo-penta-diene (Cp) ring is disordered over two positions, with site-occupancy factors 0.76 (2) and 0.24 (2). The dihedral angles between the substituted Cp ring and the major and the minor components of the disordered ring are 0.9 (5) and 6(2)°, repectively. The plane of the acrylonitrile unit makes dihed...

This analysis studied the effects modification on properties of starch-based polymer grafted with acrylonitrile (copolymers). Starch was extracted from bitter yam. The starch modified by heating solution above 70 °C and then esterified phthalic anhydride to produce a pregelatinized phthalated derivative. Acrylonitrile onto natural at 120 using calcium oxide snail shell as initiator. grafting re...

Fused deposition modeling (FDM) is a rapidly growing 3D printing technology. However, printing materials are restricted to acrylonitrile butadiene styrene (ABS) or poly (lactic acid) (PLA) in most Fused deposition modeling (FDM) equipment. Here, we report on a new high-performance printing material, polyether-ether-ketone (PEEK), which could surmount these shortcomings. This paper is devoted to...

The present work is a comparative study of possible adsorption structures of the conjugated molecule acrylonitrile on Si(001) employing the state of the art pseudopotential method, within a generalized gradient approximation to the density functional theory. In the recent literature it is proposed the interaction of acrylonitrile with Si(001) through a cycloaddition reaction of the cyano group,...

The viscoelasticity of several polymers has been determined using dynamic mechanical analysis (DMA). For the same materials the sliding wear in multiple scratching along the same groove has also been determined. The materials studied were polycarbonate (PC), polystyrene (PS), styrene/ acrylonitrile (SAN), Surlyn, polyethersulfone (PES), acrylonitrile/butadiene/styrene (ABS), polypropylene (PP),...

To develop low-cost and environmentally friendly polymeric materials for enrichment, separation, and remediation of metal ions from water, graft copolymers based on cellulose extracted from pine needles were synthesized by grafting of 2-hydroxy methacrylate (HEMA) alone and with comonomers acrylic acid, acrylamide, and acrylonitrile by benzoyl peroxide initiation. The effects of change in conce...

The residual levels and migration behavior of volatile substances were detected using HS-GC/MS for acrylonitrile-butadiene-styrene copolymer (ABS) toys, thermoplastic elastomer toys, and rubber toys made from 1,3-butadiene and styrene found on the Japanese market. The maximum residual level of these volatile substances was 2600 μg/g of styrene in ABS toys. In particular, the levels of known car...

Poly(N-cyanoethylethyleneimine) (PCEI) obtained by Michael addition of linear poly(ethyleneimine) (LPEI) with acrylonitrile provided novel nanocrystalline entities which could serve as catalytic templates affording nanosheet-based structured silica under mild conditions.

A new enzymatic process is described. Different preparations of lipase B from Candida antarctica are able to catalyse Michael-type addition of secondary amines to acrylonitrile. This new reaction widens the applicability of these biocatalysts in organic synthesis.
