STUDY OF POLY (VINYL ACETATE)/POLY (METHYL ACRYLATE) INTERPENETRATING POLYMER NETWORKS 4. Rubbery Modulus and Mutual Entanglements Between the Networks
Rubbery modulus of poly (vinyl acetate)/poly (methyl acrylate interpenetrating polymer networks (PVAc/PMA-IPNs) are determined in dynamic mechanical experim-ents
and calculated according to eq. ER = . Their comparison shows that mutual entanglements obviously exist in PVAc/PMA-IPNs
and that network I dominates the properties related. A discussion is made about the entropy change due to mutual entanglements using Binder'Frisch relationship
