Abstract
A vulcanizable rubber is modified by the addition of a resin at a temperature above the melting point of said resin. Shaped articles are formed from the resulting blend and cured without restraining pressure at a temperature below the melting point of said resin. The resin portion is present in said articles in the form of particles having a cross sectional dimension (D) not greater than 1/2 micron and a length (L) to cross sectional dimension (D) ratio of 2 or greater.
