1、acetal copolymer sheet───缩醛共聚物片
1、In the same way it is possible to copolymerize three or more monomers together.───3种或3种以上单体也能以相同的方式一起共聚。
2、Vinyl sulfonate monomers were experimentally found of lower reactivity and couldn't effectively copolymerize with MMA and MAA.───实验发现乙烯基磺酸酯类单体活性较低，与MMA和MAA单体聚合时不能很好的参与聚合反应。
3、high degree of crystallinity which limited it to copolymerize with other monomers to be used as controlled drug release materials.───的结晶度较高，不适合直接用做药物控释材料，需要与其他单体进行共聚以改善其亲水性和结晶性等性质。
4、Its branch chains having double bond can copolymerize with vinyl monomers (such as styrene or vinyl toluene) forming a thermosetting resin.───该树脂具有外双健，可与各种乙烯基单体进一步共聚形成一系列热固性树脂。
