ALTERNATING COPOLYMER GRAFT COPOLYMERS—XI. GRAFTING THROUGH MATRIX POLYMERIZATION

Pure and Applied Chemistry, 1976
The comonomer complexes generated as a result of the interaction of a donor monomer and an acceptor monomer in the presence of a complexing agent are arrayed in the form of a matrix and undergo radical initiated homopolymerization to yield an alternating copolymer.

Graft copolymers as elastomeric fibers—I synthesis of the graft copolymers

The International Journal of Applied Radiation and Isotopes, 1975
Abstract Pre-irradiation grafting, mainly with an ethyl acrylate emulsion system, has been used to produce wool and cellulosic fibers having elastomeric properties. Comparative studies using selected chemically-initiated systems were also carried out.

Graft copolymers of polysaccharides: 1. Graft copolymers of alginic acid

Polymer, 1982
Abstract Copolymers of alginic acid with acrylonitrile, methylacrylate, methylmethacrylate and ethylacrylate have been prepared and characterized by i.r. spectroscopy, differential thermal analysis and X-ray diffraction. Evidence is presented to indicate that the products are graft-copolymers and not simple mixtures of the two polymers.

Synthesis of graft copolymers with polyamide grafts

Die Makromolekulare Chemie, 1978
AbstractGraft copolymers with polybutyramide (nylon‐4) grafts onto a polystyrene backbone were synthesized by reacting 2‐pyrrolidone, in the presence of some of its potassium salt, with a backbone chain fitted with randomly distributed acyllactam sites, which act as “promoters”. To achieve the same goal with a polyisoprene backbone the latter was first

The Synthesis of Liquid Crystalline Copolymers with Block Copolymer Grafts

Macromolecular Chemistry and Physics, 2001
The synthesis of novel copolymers consisting of a side-group liquid crystalline backbone and poly(tetrahydrofuran)-poly(methyl methacrylate) block copolymer grafts was realized by using cationic-to-free-radical transformation reactions. Firstly, photoactive poly(tetrahydrofuran) macroinimers were prepared by cationic polymerization of tetrahydrofuran ...

Graft Copolymer and Block Copolymer Surfaces

1985
Homopolymers and random copolymers are relatively homogeneous in composition throughout their bulk. At the outermost molecular layer of such materials, the surface chemistry might differ substantially from the average bulk chemistry due to orientation effects, oxidation, or contamination.

Block and Graft Copolymers

Annual Review of Physical Chemistry, 1959
The volume of literature devoted to the investigation of polymeric sys­ tems continues to grow at such a great pace that it is no longer possible to review the whole of the available field in sufficient detail and sufficiently critically. Consequently, as in the past, a specific corner of the field has been selected for treatment.
