Web» Sandalwood: 12-14% resin PSE 406 Lecture 13 8 Wood Chemistry Diterpenes Physical Properties l Rosin (mixture of diterpenoids) is glass like: it slowly softens when heated –does not have a melting point l Pure resin acids are crystalline » Pimaric acid mp = 217-219°C l Tricylcicstructure quite stable: Amber l Volatilization Crystallization of polymers is a process associated with partial alignment of their molecular chains. 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 different analy…
