Reactive modification and crystallization behavior of foamed poly(butylene terephthalate)
… of preparing low density foams based on poly(butylene terephthalate) (PBT) through modification of its molecular structure and rheological characteristics by reactive extrusion. The scientific and/or engineering interpretation of the experimental data was based on fundamentals of …

Thermal characterisation of XB2-CA4 : cyclic poly(butylene terephthalate) with stannoxane catalyst
The following investigation presents the melting, polymerisation and crystallisation kinetics of XB2-CA4, an oligomer powder of cyclic butylene terephthalate with a stannoxane catalyst, which polymerises into cyclic poly(butylene terephthalate) (cPBT). When heated this material undergoes very rapid …

The thermal behaviour and isothermal crystallisation of cyclic poly(butylene terephthalate)and its blends
… crystallisation kinetics study of cyclic polyesters and its blends, in particular cyclic poly (butylene terephthalate) (c-PBT). The production of c-PBT is interesting; in fact it is different from production of conventional linear PBT since c-PBT is produced by in situ polymerisation of …

Degradable Polymers for the Controlled Delivery of Bioactive Small Molecules
… gasotransmitter-generating enzymes do. As such, polymeric delivery systems have been developed to extend the release of drugs, and in the case of gasotransmitters this more closely mimics in vivo production of HNO/H2S/RSSH. Polymeric systems have been employed to modulate gasotransmitter delivery …

Development of Thermoplastic Elastomers with Improved Elastic Properties Based on Semicrystalline Block Copolymers
… described. The first type comprises multiblock copoly(ether ester)s with semicrystalline hard segments and triblock copolymer soft segments. The second class of TPEs are systems based on ABA and ABC triblock copolymers with two glassy and one or two semicrystalline end blocks, respectively. The …
