Abstract: 
Отримано рівняння для полімерів, яке пов'язує їхню гнучкість Y, визначену в 2019 році, з лінійною ізобарною термічною розширюваністю L. Таким чином ми кількісно пов'язали термодинамічну властивість з механічною. Розширюваність важлива, оскільки різні матеріали розширюються з різною швидкістю з підвищенням температури; те ж саме стосується і стиснення в результаті охолодження. Отже, зміна температури може спричинити дезінтеграцію композиту без застосування механічної сили.
