(Table I) cyclopentene double bond. These monomers polymerization of the first and the second acrylate function.…”

The crosslinking efficiency and kinetics of a solid acrylic copolymer DCPA/EA (dicyclopentenyl acrylate/ethyl acrylate) matrix were investigated in the presence of pentaerythritol tetrakis (2‐mercaptoacetate) (PETMP) or pentaerythritol tri‐ and tetraacrylates used as multifunctional crosslinking agents. The reaction of thiol and acrylate addition was sensitized by benzophenone (BP). The crosslinking efficiency of the DCPA/EA—BP—PETMP copolymer system, illuminated at high wavelengths (λ > 310 nm), was compared with that of the DCPA/EA matrix alone and the 2‐component system copolymer DCPA/EA–BP. The concentrations of photosensitizer and crosslinking agent were varied from 1 to 10 mass %. The kinetics of tetrafunctional thiol addition and cyclopentene (pendant group of the DCPA/EA matrix) disappearance was followed through Fourier transform infrared (FTIR) and by determining the gel content. © 1997 John Wiley & Sons, Inc.

“…Figure 4 shows typical high-damping polymers for comparison; such materials exhibit a broad single transition through room temperature rather than two sharp peaks above and below room temperature. Sperling et al [27] report on the dynamic mechanical behavior of the two series of heterogeneous latexes listed in Table 1. In series I, the polystyrene and poly- butadiene are incompatible, while in series II, the poly(n-butyl acrylate) and poly(ethyl methacrylate) are semicompatible.…”

Recent developments in our laboratories have led to major advances in elucidating the factors controlling latex particle morphology in styrene-polystyrene systems. This paper discusses the relevance of these advances to the preparation of impact polymers from heterogeneous latexes. The results of some studies on the dynamic mechanical behavior of heterogeneous latexes is also reviewed. A thorough understanding and complete correlation of the influence of syntesis variables on impact behavior remains to be established.

“…N THE PAST five years, several investigators [1][2][3][4][5][6][7][8][9][10][11][12][13] have been studying a parIticular type of polymer blend in which various degrees of chain entanglement (depending on the polymers used and the method of blending) have been stabilized by homocrosslinking of the two polymers. In this manner, interpenetrating polymer networks (IPN) have been produced.…”

A nomenclature scheme for various types of interpenetrating polymer networks (IPN) based on morphology, topology, and method of synthesis is presented. In this scheme, IPN is the generic name of all polyblends of this type, regardless of their origin, as opposed to Sperling's recent classification of polyblends and graft copolymers, (Polymer Preprints, 14, (2), August, 1973), in which the various types of IPN's are given separate classifications under the generic heading of polyblends. I NTRODUCTI ONN THE PAST five years, several investigators [1-13] have been studying a parIticular type of polymer blend in which various degrees of chain entanglement (depending on the polymers used and the method of blending) have been stabilized by homocrosslinking of the two polymers. In this manner, interpenetrating polymer networks (IPN) have been produced. They have been shown to possess interesting properties and varying morphologies [1][2][3][4][5][6][7][8][9][10][11][12][13] .Because of the different methods of synthesis and varying compatibilities of the individual polymers, blends with different microstructures have resulted. It is the purpose of this paper to name these various structures according to their morphology and topology, as well as their method of syntheses.
