[0127] Method for defining the microstructure of liquid rubber resins and definition of side groups

[0128] The microstructure of liquid rubber resins, particularly those listed in the table below, was determined using the 1H nuclear magnetic resonance (NMR) method using a Bruker Avance III 400 MHz spectrometer with CDCl3 as solvent. Analytical protocols are detailed in: Iranian Polymer Journal 12(6), 2003, pp. 515-521, and Polymer Engineering and Science, 2007, pp. 87-94; and in Ohio, October 11-13, 2016 Compilation of proceedings presented at the Fall 190th Technical Meeting of Rubber Division, ACS Cleveland, OH, October 11-13, 2016.

Abstract

A curable liquid rubber composition including at least one liquid polyene component and at least one heat activated crosslinking agent. The liquid polyene component may be a single polyene or a blend of polyenes. In one embodiment, the liquid polyene component may contain on a molar basis, at least one monomer that results in at least 45 molar percent of C2-C13 pendant groups. In another embodiment, the liquid polyene component may contain on a molar basis at least one monomer that results in at least 20 molar percent of C2-C5 pendant groups, and at least one monomer that results in at least 7 molar percent of C6-C13 pendant groups. After curing, the liquid rubber composition may have a loss factor greater than 0.51, a maximum loss factor temperature greater than -10DEG C, and a swelling ratio in toluene from 40% to 170% by weight.
