“…Most of MDI/PMMA-modified starch was deeply embeded into the SBR matrix. As reported in our previous article, 16 without MDI, when starch concentration exceeded 30 phr, the PMMA-modified starch agglomerates with particle size approximate 1-10 μm extensively appeared due to the strong hydrogen bonding between particles. However, in the present research, with the addition of MDI, even when 40 phr of starch were incorporated, there were no agglomerates observed.…”

“…PMMA-modified starch emulsions with 10, 20, 30 and 40 phr of starch were synthesized via emulsion polymerization using potassium persulfate (KPS) as initiator and dodecylbezenesulfonic acid sodium salt (DBS-Na) as emulsifier, as reported in our previous research. 16 Coupling agent 4,4-methylene diisocyanate (MDI) with high purity (98%) was purchased from Sigma-Aldrich Co. Figure 1 shows the molecular formula of MDI. Carbon black (CB) Corax N550 (FEF) with nitrogen surface area 42 m 2 /g was purchased from Evonik Co. Other chemicals and rubber additives were commercially available and used as received.…”

“…Although the smaller particle size and better dispersion were achieved by using this method, the interfacial bonding between modified starch and SBR matrix was still weak, showing up in the slight improvement in the 300% modulus. 16 Therefore, it is very essential to build the strong chemical interfacial bonding between modified starch and SBR matrix.…”

ABSTRACT：Methylene diisocyanate (MDI) was investigated as a novel interfacial modifier to enhance the performances of poly(methyl methacrylate)-modified starch/styrene-butadiene rubber (PMMA-modified starch/SBR) composites. Owing to the formation urethane linkage on one side and π-π adhesion on the other side, MDI acted as an intermediated linkage role in the PMMA-modified starch/SBR interfaces, which was evidenced by the morphological, mechanical, dynamic mechanical and thermal decomposition studies. As a result, the presence of MDI significantly improved the mechanical properties and thermal stability of PMMA-modified starch/SBR composites. In addition, the effect of starch concentration on the various performances of the resulted MDI/PMMA-modified starch/SBR composites, such as morphology, vulcanization characteristics, mechanical properties, toluene swelling behavior, and thermal stability were investigated and discussed in detail. The obtained MDI/PMMA-modified starch/SBR composites exhibited superior mechanical properties to carbon black/SBR (CB/SBR) composites, demonstrating the potential use of the renewable starch as a substitute for CB in the rubber compounds. 요 약：메틸렌 디이소시아네이트(MDI)가 폴리(메틸 메타크릴레이트)

Acrylonitrile butadiene rubber (NBR)/bentonite (Bt) nanocomposites were synthesized by an one-step method in NBR latex with (3-Mercaptopropyl)trimethoxysilane (MPTMS) as a compatilizer. The nanocomposites were compounded with curing additives and then vulcanized. The prepared vulcanizates were characterized by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The curing properties and mechanical properties were also investigated. The thermal properties were studied with thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The morphology was investigated by field emission-scanning electron microscopy (FE-SEM). By swelling test, the swelling ratio and the crosslinking density were achieved. The hydrolyzation and condensation of MPTMS was identified by FTIR while the intercalated/exfoliated structure of Bt was determined by XRD. It was evident that the mechanical properties of the nanocomposites were significantly improved compared with the neat NBR. The welldispersed bentonite particles and effects of MPTMS were supported by the images from FE-SEM. The results of TGA showed that the fastest weight-loss temperature (T max ) was elevated by over 10

This study analyzed the major injection molding process parameters that affect the impact performance of low-density polyethylene(LDPE) by orthogonal experiment method. Response surface methodology was proposed to analyze the significant influence factors, and then determined optimal parameters setting of injection molding process. The results show that melting temperature and packing time are the two significant factors influence the impact performance of plastic product. Logical process parameters combinations of melting temperature, packing time and filling time are achieved by further analysis using response surface methodology. By using the optimal parameters, the arrangement of the fillers is improved, as a result, the impact performance of the filler composite is enhanced.Keywords: injection molding process parameters, impact performance, orthogonal experiment, response surface methodology Анализируются основные параметры процесса литья под давлением, которые влияют на характеристики полиэтилена низкого давления (ПНД) методом прямого эксперимента.
