(1) thaum lub thawv yas ntim ua ke nrog cov pob zeb, cov khoom me me. Lub hauv paus ntawm cov yas thaij yas yuav muab tso rau hauv txoj hlua polymer, tsis muaj zog zuj zus ntawm cov kabmob polymer, nce cov teebmeem ntawm cov yas thooj plawg ua kom qhov kev ncua deb ntawm lawv, qhov nce ntawm cov xov tooj txawb ntawm cov xov tooj ntawm tes yuav yog. Txo txoj kev nkag siab ntawm cov zauv ntawm cov xaim hluav taws xob, qhov ntxhib ntawm qhov kub qis tuaj yeem tsim cov iav hloov, thiaj li ua kom cov yas yas ntxiv. Nws tuaj yeem pom tau tias txoj cai ntawm kev tiv thaiv cov kab mob khaub thuas tiv thaiv no yog ib qho laj thawj loj rau txoj kev ua haujlwm rau cov yas los ntawm lub gravitational thiab entanglement ntawm polymer chains.
(2) cov qauv ntawm cov hlau polymer tseem cuam tshuam rau cov chains polymer ntawm lub ntiajteb txawj nqus, tshwj xeeb tshaj yog cov khoom ntawm txhua pawg polymer chains, loj zog chains nrog pawg polar pawg, nrog molecular saw tsis polar pawg kev sib tshuam, thiaj li ua kom muaj zog ncov qaum pawg ntawm cov polymer yog yooj yim rau molding. Koj tuaj yeem ntxiv cov kab mob khaub thuas txias, ua npau suav nrog polymer polar pawg kev sib tshuam, li no weakening tus attraction ntawm polymer, kuj mus txog lub hom phiaj ntawm yas lim.
