Synthesis of Flower‐Like Polybutadiene
Macromolecular Chemistry and Physics, 2017Synthesis of complex macromolecular architectures exhibiting no chain ends such as flower‐like polymers is still of interest in the aim of investigating their physicochemical properties. For this purpose, poly(3,4‐dimethyl maleic imidoethyl acrylate)‐block‐polybutadiene‐block‐poly(3,4‐dimethyl maleic imidoethyl acrylate) triblock copolymer is ...

Journal of Polymer Science, 1955
AbstractA detailed study has been made of the intrinsic viscosity‐molecular weight relationship for a polybutadiene prepared at 50°C. and one prepared at 5°C. Original fractions were at least twice refractionated from very dilute solutions in an attempt to obtain fairly sharp distributions. Fox‐Flory K constants are observed to decrease with increasing

Cis‐trans isomerization in polybutadiene
Journal of Polymer Science, 1957Abstract About twenty years ago, in an effort to transform natural rubber into gutta-percha, Meyer and Ferri irradiated a solution of Hevea in cyclohexane with ultraviolet light, but were unable to detect any cis-trans isomerization in polyisoprene.

Liquid polybutadiene adhesives
International Journal of Adhesion and Adhesives, 1984Abstract Adhesives based on sulphur-cured liquid polybutadiene polymers can be formulated to suit a wide range of applications from joint sealing to structural bonding. This enables some problems to be overcome, especially in the automotive industry; for example, polybutadienes withstand the high paint stoving temperatures used for cathodic ...
