Pseudo-semi-interpenetrating polymer

Semi-interpenetrating polymer networks (semi-IPN, also called pseudo-IPN)... 

A semi-interpenetrating polymer network (SIPN) is a combination of a network polymer and a linear polymer. A SIPN is usually prepared by the polymerization of a multifunctional monomer in the presence of a linear polymer [1], Qo derivatives and Ciso-containing polymers form aggregates in solution and in the solid state [2-18]. For double-C o-end-capped polymers in which both ends of each polymer chain are capped with Cgo, the aggregation of C,so leads to a network-like material. Therefore, a combination of a double-C,so-end-capped polymer and a linear polymer produces a material resembling a SIPN and is termed a pseudo-SIPN. This chapter discusses the mechanical and optical properties of some pseudo-SIPNs involving double-C,so-end-capped polymers. 

Pseudo or semi-IPNs are combinations of linear with crosslinked polymers resulting in various degrees of interpenetration. (28-34)...
