聚醋酸乙烯酯/聚丙烯酸甲酯互穿网络聚合物的研究Ⅴ.互穿缠结对相区结构的稳定作用
摘要:
用定量的甲苯溶胀聚醋酸乙烯酯/聚丙烯酸甲酯互穿网络聚合物(PVAc/PMA IPN),使体系处于分相的热力学条件;或醇解其中的PVAc网络,即增加两组份的化学不相容性.动态力学谱和透射电镜等结果表明,IPN和网络Ⅰ的交联密度较高的半IPN试样,没有发生进一步的相分离,证明网络互穿缠结是永久性的物理缠结,并且有强迫互容作用的存在.

STUDY OF POLY(VINYL ACETATE)/POLY(METHACRYLATE) INTERPENETRATING POLYMER NETWORKS Ⅴ.PHASE STABILIZATION FROM MUTUAL ENTANGLEMENTS BETWEEN NETWORKS
Abstract:
Poly(vinyl acetate)/poly(methacrylate) interpenetrating polymer networks(PVAc/PMA IPNs) and semi-IPNs were swollen in toluene under the thermodynamic condition of phase separation,or the PVAc component of the IPNs was alcoholyzed to decrease the compatibi-lity between two components.No phase separation was found in IPNs and semi-IPNs with high crosslink density of network I.It is indicated that the mutual entanglements between the two networks is permanent physical entanglements and the phase of the IPNs is stable.
