In this study, two polymerization technology were designed trough the molecular control engineering, and technological improvement and the optimal formulation. The results show: for the technology 1, ultra-high molecular weight silicone oil is prepared under the condition as follows: the polymerization temperature is 90 ° C, the amount of catalyst is 0.0001%,hydrolysates amount of 0.08% (relative monomer content). By adding the amount of 10% feeling formation agent, the target products and the optimal apply portfolio period is availed; Considering the technology 2, The three components coated with silicone rubber that meet the requirements can be prepared under the condition as follows: the polymerization temperature is 50 ° C, the amount of catalyst is 0.01%. Graft polymer main chain was 1% (25% relative toluene solution in terms of silicone oil) and the initial oil viscosity is 1000000 mPa.s .Comparatively speaking, the process of technology 1 is more difficult, and the technology 2 relatively needs more curing time, all have their pros and cons.
