Mechanochemically initiated copolymerizations. 5. Characterization of some binary and ternary copolymers obtained mechanochemically by vibratory milling

Abstract

Vibratory milling proved to be a method of mcclianochenlical initiation of some copolymerization reactions for binary and ternary systems of vinyl comonomers. Some physico-chemical properties of t h e copolymers obtained b y this method are presented. The structure of t h e reaction products was characterized by means of I R and ESR spectroscopy, vapourphase osmometry and elemental analysis. Mechano-chemisch initiierte Copolymerisation. 5. Charakterisierung einiger biniirer und terniirerCopolymere, die mechanochemisch durch Schwingmahlung erhalten wurden Jlie Schwingmahlung wurde zur mechano-chemisehen Initiicrung der Copolymerisation von Vinylmonomcren eingesetzt. Einige physikalisch-chemische Eigenscliaftcri dcr auf diese Weise erhaltenen Copolymere werdcn mitgeteilt. I)ic St,ruktur der Reaktiorisproduktc wurde mittels IR-urid ESR-Spcktroskopie sowic durch Dampfdruckosmometrie und Elcmentaraualysc charakterisiert. Mexawxu.wuuecwm cononu.uepu3ayu~. 'lacmb .i.

The mechanochemical synthesis of polymers

“…125,138 Continuing studies by Oprea in the 1980s and by Kuzuya in the 1990s covered many of the vinyl monomers known to undergo polymerisation (Scheme 1). 18 The adopted strategy was used to convert (meth)acrylates, 19,130,139–145 (meth)acrylamides, 125,126,141,146 styrenes, 128,141,147–150 and other structurally diverse vinyl monomers 149–152 into the corresponding polymers under solvent-free ball-milling conditions. Moreover, the copolymerisation of these monomers has also been investigated, 125,130,140,149,153–155 as is discussed below.…”
