The morphology of crystalline polymers

摘要: This article is a short reveiw of the development our knowledge on texture crystalline polymers. It begins by quoting conventional fringed micelle model which has proved so useful for much earlier workon crystallization in shown further how gradually new ideas had to be invoked order account textural elements. The most widely observed these spherulite. desired that spherulites have characterstics fibrous morphology and may offer consist twisted orientation molecules within relation between observation studies kinetic briefly dicussed. Recent observations polymer single crystals are quoted some detail. establish hitherto unsuspected link polymeric simple substances, while other hand, they necessite introduction concept, concept chain-folding. Owing folded chain configuration such havs unusual properties, described, thus lesding up recent developments subject. possible connections various elements dicussed brief together with generalizations seem emerge at present.
