Research of properties of the polyadd-modified polyether supermole-cule;

It is achieved the level of imported oil that the properties of environmental protection compressor oil to automobile air-conditioner developed with modified polyether,and it is exhibited the developed environmental protection compressor oil to automobile air-conditioner can satisfy the use requirement by practical application.

The alcohol -amine modified polysiloxane(PAPS)reacted with sodium chloroacetate to form the polyether-modified betaine functional siloxane surfactant(PBPS)via quaternary ammonium reaction,the major influencing factors were studied by orthogonal design test,and PBPS applied to fatliqouring.

Research on Technological Performance of MPPO Injection Moulding;

IMPROVING OF MPPO RADAR ANTENNA INSULATION RING;

The structure characteristic of the locknut of color kinescope and the moulding characteristic of MPPO are analyzed.

The synthesis, curing mechanism and technology progress of silicon-modified polyether were brifely introduced.

By using the analysis technique of 13C-NMR, together with the analysis methods of IR, UV, WAXD and TGA, and referring 13C-NMR spectrum of Sadtler standard, five modified PPO samples from oversea companies are identified.
