Chemical structures and physical properties of cured segmental polyurethanes

Autor: Adolf Balas, Helena Janik

Publikováno v: Polimery. 54:195-201

Segmental polyurethanes (PUR) obtained in two-stage syntheses from oligomeric α,ω--dihydroxy(ethylene-butylene adipate) and two different aromatic diisocyanates: diphenylmethane 4,4'-diisocyanate (MDI) or MDI modified with carbodiimide diisocyanate

Dynamic mechanical properties and thermal degradation process of the compositions obtainedfrom unsaturated poly(ester urethanes) cross-linked with styrene

Autor: Józef Haponiuk, Lidia Jasińska, Adolf Balas

Publikováno v: Journal of Thermal Analysis and Calorimetry. 93:777-781

Dynamic mechanical and thermal properties of poly(ester urethanes) (PEU) cross-linked with styrene have been studied. The investigated polyurethanes were obtained from 4,4′-diphenylmethane diisocyanate and unsaturated oligo(alkyleneester)diol based

Thermal and dynamic mechanical analysis of cross-linked poly(esterurethanes)

Autor: Stefan Jurga, Józef Haponiuk, Lidia Jasińska, Grzegorz Nowaczyk, Adolf Balas

Publikováno v: Journal of Thermal Analysis and Calorimetry. 88:419-423

New cross-linked poly(esterurethanes) (PEU) based on unsaturated olygo(alkyleneester)diol (OAE), 4,4’-diphenylmethane diisocyanate (MDI) and styrene or methyl methacrylate as curing monomers were prepared. The synthesis of PEU was performed in two

Epoxy resins and polyurethanes — mutual modifying influence. Part II. Interpenetrating polymer networks (IPN)

Autor: Adolf Balas, Tomasz Pokropski

Publikováno v: Polimery. 48:591-597

The methods of epoxy resins (EP) and polyurethanes (PUR) mutual modification leading to the formation of interpenetrating polymer networks (IPN) and graft polymer networks (graft-IPN) were presented on the basis of literature data. Main aim of EP mod

Qualitative identification of isocyanurate rings in urethane-isocyanurate elastomers and their hydrolyzates

Autor: Adolf Balas, Roksana Samborska-Skowron

Publikováno v: Polimery. 48:371-374

It has been stated that reliable qualitative identification of isocyanurate rings directly in urethane-isocyanurate elastomers (EUI) can not be realized using ATR method. Such identification becomes possible only on the basis of the analysis of EUI h

DSC and thermal stability investigation of novel poly(ester-ether) glycols and poly(ester-ether)urethanes

Autor: Adolf Balas, Janusz Datta

Publikováno v: Journal of Thermal Analysis and Calorimetry. 74:615-621

A new group of poly(ester-ether) glycols was obtained by polycondensation of adipic acid with poly(alkylene glycol) or of adipic acid with mixture of poly(alkylene glycol) and ethylene glycol. Poly(ester-ether) glycols were synthesised in a two-step
