Feature and use: It tests melt flow rate of high polymer under mucosity flow state.It was expressed by MFR or MVR.It suits for testing polycarbonate,FI plastic and nylon under higher melt temperature. It suits for testing polyethylene、polystyrene、polypropylene、ABS colophony and polyformaldehyde colophony under lower melt temperature.

特点及用途：熔体流动速率仪是用来测定各种高聚物在粘流状态时的熔体流动速率，在一定的温度和负荷下，熔体每10min通过标准口模的质量或体积，用MFR或MVR来表示，它既适用于熔融温度较高的聚碳酸脂、聚芳砜、氟塑料、尼龙等工程塑料，也适用于聚乙烯、聚苯乙烯、聚丙烯、ABS树脂、聚甲醛树脂等熔融温度较低的塑料测试，广泛应用于塑料生产、塑料制品、石油化工等行业及有关院校、科研单位和商检部门。

Firstly, micron-size monodisperse polystyrene particles were prepared by emulsifier-free polymerization. Then the photo-initiator with double bond and ester group were attached on the surface of the PS particles by copolymerization using "starve" addition together with styrene. Finally both poly and poly(N-isopropylacrylamide) as hybrid hairy homopolymers were grafted on the surface of the PS particles by "grafting from" photo-initiation with sequential addition of AA and NIPA.
