หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : The Effect of Process Factors on the Mechanical Properties of Styrene-NR Elastomers Containing Natural Rubber-Graft- Polystyrene) ผู้เขียน:ดร.ธาริณี นามพิชญ์, รองศาสตราจารย์, Polchit Buakaew สื่อสิ่งพิมพ์:pdf AbstractStyrene-NR elastomers containing natural rubber-graft-polystyrene were prepared by an emulsion polymerization using potassium persulfate as an initiator. The effect of process factors on tensile strength was investigated by varying the temperature, rubber-to-monomer ratio, and initiator and emulsifier contents from 50 to 64 ?C, 1.5 to 9, 0.8 to 1.4 g, and 4.5 to 6.5 g, respectively. Experimental results indicated that the tensile strength increased with an increase in reaction temperature, rubber to monomer ratio, and initiator and emulsifier contents. |
