Abstract

Search of new materials in industry remains relevant today. Recently intensively production and application of the elastomers capable to big reversible deformations develops. Rather new elastomer syndiotactic 1,2-polybutadiene (1,2-SPB) is among such polymers. The elastomer is perspective for use in various areas of equipment requiring a good combination of plastic and as an additive in polymer materials.This paper presents the results of study of the elastomer (1,2-SPB) which was first obtained by Japanese scientists G. Natta and Corradini. Corporation JapanSyntheticRubber (JSR) (Japan) obtains 1,2-SPB with content of 90% 1,2-bonds and low degree of crystallinity (15-30%). In Russia, where getting of 1,2-SPB mastered relatively recently, developed experimental batches of polymer with a content of 1,2-bonds more than 85% and crystallinity 20-50%. Really this elastomer represents composition of nanocrystals and an amorphous phase. New method in studying of structure of an elastomer is atomic force microscopy (AFM) which has extreme resolution in all three directions. Resolution of microscopes are share of nanometers that allows to observe atoms. AFM is a widely used instrument for research in various fields of science. By means of atomic force microscopy image of deformed elastomer 1,2-SPB surface was taken, which allows to analyze structure many different hard materials - polymers, glasses, ceramics, plastics, metals, semiconductors. The basic chemical and physical properties, the structure of syndiotactic 1,2-polybutadiene was observed. The conditions of formation of spatially ordered lamellar structure at deformation of syndiotactic 1,2-polybutadiene are discussed.
