The lack of crystalline cross-linked polymers is often cited as evidence in support of this view (1).Recently,weembarkedona program aimed at challenging this notion by constructing porous, crystalline, covalent or-ganic frameworks (COFs) solely from light elements(H,B,C,N,andO)thatareknownto

These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named spherulites. Polymers can crystallize upon cooling from melting, mechanical stretching or solvent evaporation. Crystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by differe… great cuts wethersfield ct
