Synthesis and mechanical properties of high impact polystyrene with in situ bulk polymerization toughened by one‐pot Nd‐based styrene–isoprene–butadiene terpolymer rubber

15-Jun-2016 | Tingting Li, Li Li, Qiang Xu, Yurong Wang, Yang Li, Journal of Applied Polymer Science, 2016

ABSTRACT High impact polystyrene (HIPS) resins were obtained with in situ bulk polymerization toughened by styrene–isoprene–butadiene terpolymer rubber (SIBR). SIBR prepolymer was prepared through selective polymerization of styrene (St), isoprene (Ip), and butadiene (Bd) in St with ...

Poly1‐hexene: New impact modifier in HIPS technology

24-May-2016 | Ahad Hanifpour, Naeimeh Bahri‐Laleh, Mehdi Nekoomanesh‐Haghighi, Seyed Amin Mirmohammadi, Journal of Applied Polymer Science, 2016

ABSTRACT Poly1‐hexene was prepared using a conventional heterogeneous Ziegler–Natta catalyst and its stereoregularity was characterized using 13C‐NMR analysis. New kind of high impact polystyrene (HIPS) was prepared by radical polymerization of styrene in the presence of different amounts of ...

Effect of carbon black on the thermal degradation and flammability properties of flame‐retarded high impact polystyrene/magnesium hydroxide/microencapsulated red phosphorus composite

21-Mar-2016 | Jichun Liu, Yanbin Zhang, Yingbin Guo, Chang Lu, Bingli Pan, Shuge Peng, Junying Ma, Qingshan Niu, Polymer Composites, 2016

Nanosized carbon black (CB) was introduced to flame‐retarded high impact polystyrene/magnesium hydroxide/microencapsulated red phosphorus (HIPS/MH/MRP) composite by melt compounding. The effect of CB on the thermal degradation and flammability properties of the HIPS/MH/MRP composite was ...

Analysis of Flame Retardancy in Polymer Blends by Synchrotron X-ray K-edge Tomography and Interferometric Phase Contrast Movies

18-Feb-2016 | Mutairu B. Olatinwo; Kyungmin Ham; Jonathan McCarney; Shashidhara Marathe; Jinghua Ge; Gerry Knapp; Leslie G. Butler, Journal of Physical Chemistry B, 2016

Underwriters Laboratories 94 test bars have been imaged with X-ray K-edge tomography between 12 and 32 keV to assess the bromine and antimony concentration gradient across char layers of partially burnt samples. Phase contrast tomography on partially burnt samples showed gas bubbles and ...

Emissions of Ultrafine Particles and Volatile Organic Compounds from Commercially Available Desktop Three-Dimensional Printers with Multiple Filaments

15-Jan-2016 | Parham Azimi; Dan Zhao; Claire Pouzet; Neil E. Crain; Brent Stephens, Environmental Science & Technology, 2016

Previous research has shown that desktop 3D printers can emit large numbers of ultrafine particles (UFPs, particles less than 100 nm) and some hazardous volatile organic compounds (VOCs) during printing, although very few filament and 3D printer combinations have been tested to date. Here we ...

Studies on mechanical behavior high impact polystyrene/vinyl clay nanocomposites: Comparison between in situ polymerization and melt mixing

21-May-2015 | Praseetha P. Nair, George K.E., Jayakrishnan N., Polymer Composites, 2015

A comparative study on various synthesis methods like melt mixing (MM) and in situ polymerization (ISP) of high impact polystyrene/vinyl clay nanocomposites (HIPS/VNCs) is attempted here. In ISP, nanocomposites were prepared by mixing vinyl clay (VC) and poly butadiene rubber (PBR) in styrene ...

Novel injection molding foaming approaches using gas‐laden pellets with N2, CO2, and N2 + CO2 as the blowing agents

25-Jun-2013 | Xiaofei Sun, Lih‐Sheng Turng, Polymer Engineering and Science, 2013

A novel method of producing injection molded parts with a foamed structure has been developed. It has been named supercritical fluid‐laden pellet injection molding foaming technology (SIFT). Compared with conventional microcellular foaming technologies, it lowers equipment costs without ...

Synthesis and Characterization of High Impact Polystyrene from a Heterogeneous Styrene‐Rubber‐Polystyrene Solution: Influence of PS Concentration on the Phase Inversion, Morphology and Impact Strength

15-Apr-2013 | Florentino Soriano‐Corral, Graciela Morales, Pablo Acuña, Enrique Díaz‐Barriga, Berenice Arellano, Claribel Vargas, ..., Macromolecular Symposia, 2013

Abstract High Impact Polystyrene (HIPS) was synthesized by free radical polymerization through the bulk‐bulk technique. Polybutadiene (PB) and/or poly(butadiene‐b‐styrene) copolymer (S:B = 30:70) (at 8 wt‐%) were used as impact modifiers in the presence of 0, 5 and 7.5 wt‐% of polystyrene (PS) ...
