1.As the influence on Tg by the former may exactly be offset by that of the latter, Tg kept almost unchanged. 2.The small increase of R1.4 crosslink density Hardly can compensate the influence of reduced Xc on mechanical performances. 3.Nevertheless, in this system, crosslink density is not considered to be a chief factor for the degradation as the increase of crosslink density is always companied by a decrease of Xc. |
