Проведенные исследования показывают, чтодаже при наличии одной популяции кристаллов, сформированных в процессеизотермической кристаллизации, в ходе нагревов можно получить два пикаплавления,чтоподтверждаетпредложеннуюмодельплавлениякристаллической структуры полимера.С одной стороны, данная работа носит прикладной характер, так как былпредложен совершенно новый метод исследования, способный проводитьэксперименты, ранее недоступные научному сообществу; с другой стороны, былитакже затронуты фундаментальные научные вопросы. Полученные результатывполне успешно могут объяснить сложный феномен множественного плавления ипроцессов плавления-рекристаллизации полужесткоцепных полимеров.
Данныйвопрос обсуждался мировым научным сообществом уже на протяжении 50 лет и ненаходилоднозначногоответаприиспользованиихимических методов.127классическихфизико-Список литературы1. Mandelkern L.
