It is thinning, there is advantage on enlarged product, occur being molded the product defects such as insufficient, warpage from reducing.However it uses
The method of peroxide still will produce the residual of peroxide, and can not fundamentally remove these residuals, with pushing away for time
Shifting will continue to cause polymer degradation or crosslinking, to influence the performance of end article.
The present invention is directed to be passed through under the premise of not applying any peroxide using the ultrasonic energy of clean environment firendly
Ultrasonic technique causes propylene-based elastomeric fusion-grafting functional monomer, to prepare polarity propylene-based elastomeric, widens it and answers
The roads Tiao Xin are opened up with range.
