摘要： Process for the production of latices of conjugated diene polymers and conjugated diene copolymers with vinyl compounds by emulsion polymerization comprising(a) a first polymerization stage in the presence of the monomer as a phase separate from the polymer being formed,(b) an intermediate stage in which the monomer is added in quantities such that the conversion of the monomer at the end of each individual addition exceeds 45%, and(c) a final stage in which the reaction is carried to completion.

摘要： Cyclized polydienes devoid of crosslinked fractions are prepared by polymerizing conjugated diolefins in solution in a solvent consisting of a mixture of saturated hydrocarbons with 20-95% by weight, with respect to the mixture, of chlorinated saturated hydrocarbons, in the presence of from 0.1 to 10 moles for each 100 moles of diolefins, of a catalyst of the formula R.sub.n Al Cl.sub.3-n, where R is an alkyl radical with 1-6 carbon atoms and n is from 1 to 1.5.These cyclized polydienes can be used in coating formulations.
