Texto completoLignin is the most abundant component of wood after cellulose and is separated from whilepaper production. Within this lingo-cellulosic biomass, in case of graminous, ferulic acid is a crosslinkingagent binding lignin to polysaccharide fibers to increase its mechanical properties. If lignin iscomplex and poorly degradable, ferulic acid, as it is present free, is extractible in alkali media frommany resources (beetroot pulp, wheat, corn, rice...).By its aromatic nature, this p-hydroxycinnamic acid seems interesting to prepare new polymersincorporating biobased aromatic units. Indeed, if biobased polymers are more and more nowadays,today biobased aromatic units are still missing.In this aim, into the APSYNTH team, we developed a new class of biobased bisphenols obtainedthrough enzymatic catalysis. These bisphenols were then implicated in different strategies to developnew copolyesters, polyurethanes and polyphenolic oligomers. This work describes the synthesis andcharacterization of this new bisphenols derived from ferulic acid, as well as the resulting polymers

Texto completoŠiame darbe nuodugniai ištirtos gamybinių polietilentereftalato (PET) atliekų susidarymo vietos, priežastys bei jų savybės. Pasiūlyti skirtingi cheminio perdirbimo būdai ir sąlygos kiekvienai gamybinių PET atliekų rūšiai. Vykdant gamybinių PET atliekų glikolizę etilenglikoliu, pasiekta didesnė negu 85 % bis(2-hidroksietilen)tereftalatо išeiga. Peresterinant gamybines PET atliekas dietilenglikoliu (DEG) ir naudojant funkcinius priedus glicerolį (GL) ir/arba adipo rūgštį (ADR), susintetinta serija aromatinių poliesterpoliolių (APP), besiskiriančių savo klampa ir kitomis savybėmis. Pirmą kartą nuodugniai ištirta ir matematiškai aprašyta peresterinimo reakcijos mišinyje esančių funkcinių priedų įtaka APP klampai. APP, susintetinti peresterinant gamybines PET atliekas DEG ir turintys ADR ir/arba GL fragmentų, yra mažai linkę kristalintis ir stabilūs saugant juos kambario temperatūroje. APP klampa mažai priklauso nuo metaloorganinio katalizatoriaus cheminės sudėties ir jo koncentracijos. Naudojant PET peresterinimo metu gautus APP ir diizocianato perteklių, susintetintos poliuretano-poliizocianurato (PU-PIR) putos. Putos, gautos iš APP, kuriuose yra GL ir/arba ADR fragmentų, pasižymi geromis fizikomechaninėmis savybėmis ir dideliu terminiu stabilumu, joms degant išsiskiria mažesnis šilumos ir dūmų kiekis. Atliekant degumo bandymus nustatyta, kad PU-PIR putos atitinka reikalavimus, taikomus Е klasės statybinėms konstrukcijoms ir elementams.

A series of polyurethanes and copolyurethanes was prepared by solution polymerization using various imide diols with hexamethylene diisocyanate(HMDI), 4,4'-diphenyl methane diiso- cyanate (MDI), 2,4- toluylene diisocyanate (2,4-TDI) and iso- phorone diisocyanate (IPDI), respectively. Thermal stability, solubility and liquid crystalline properties of these synthe- sized polyurethanes were examined. The influence of the length of flexible chain on the properties of these polymers was studied. The pyromellitic diimide unit could be played as the role of the mosegen for a liquid cryatalline polymer. However, the thermal stability of this liquid crystal polymer was not good. Therefore, longer rodlike mesogen was introduced, the obtained polymer possesed better liquid crystalline properties.

Polyurethane (PU) has already found extensive application in many diversified field. One disadvantage of PU is their poor thermal properties in high tempertature. In order to improve the thermal properties of PU, we incorporated three kinds of chain extender contain Bis(4-Aminophenyl) Sulfone [Bisaminol S]、Bis(4-Hydroxyphenyl) Sulfone [Bisphenol S] and 3,3’,4,4’-Diphenylsulfonetetracarboxylic Dianhydride [DSDA] as chain extender separately. All of three different chain extenders have sulfone group and benzene structures, so as to improve their thermal stability. In this study, PTMG is the soft component. MDI and three different chain extenders are the hard component. There were shown different thermal stability among chain extender. There were made a series of polyurethane within different chain extenders by two steps. Both of traditional polyurethane and ameliorative polyurethane will do a series of tests and analyses. In our experiment, the formation of copolymer were synthesized successfully. There were not only proved by FTIR and H1 NMR spectroscopy.But also the intrinsic viscosity of ameliorative copolymers had rise obviously. For the thermal properties, the initial degradation temperature of ameliorative copolymers were higher than tradition polyurethane and it showed that the second degradation step increased as the hard segment content. Tgs and Tgh were all higher than traditional polyurethane. For the mechanical properties, the tenacity of ameliorative copolymers were all higher than traditional polyurethane.
