Ambient temperature self-crosslinking acrylic latexes were prepared through semicontinuous emulsion polymerization using 3 different polymerizable alkoxysilanes, i.e. vinyl tri silane (A172), Vinyl triethoxy silane and γ-methacryloxypropyl trimethoxy silane (A174). The hydrolysis of these siloxanes under different pH was characterized, and dependence of the latex and polymer properties on these siloxanes and their incorporated amounts in the polymers was studied.

The first grade is 14.7cm/kg, the fifth is 3.2cm/kg, and the sixth is lower than 2.0 cm/kg.Linked the Paull's(1996) conclusioned that the ethylene quantity was fewness at the first grade, and toped at the third to four grade, then droped rapidly, but the papaya fluit neither had the best flavor,nor became mature completely when ethylene quantity was tiptop.So we used the rigidity standard not the ethylene quantity to choose specimen.
将采后番木瓜果实按果皮颜色可分为六级,其中一级硬度为14.7 kg / cm2,六级为2.0 kg / cm2 ,结合Paull(1996)对采后番木瓜乙烯变化的结论:乙烯含量在果色破色前最微,到开始变软时达到高峰以后迅速下降,而此时番木瓜还没有达到食用风味最佳,也没有达到成熟,因此相比而言我们使用硬度为指标进行选择比较方便可行。
