MICELLIZATION BEHAVIOR COMPARISION OF POLYPEPTIDE GRAFT COPOLYMER AND BLOCK-GRAFT COPOLYMER IN ETHANOL
(Sociedad Chilena de Química, 2010)
Monolayers and Thin Films of Dextran Hydrophobically Modified
(SOC BRASILEIRA QUIMICA, 2010)
A series of biodegradable graft copolymers were synthesized by grafting epsilon-caprolactone over dextran of different molecular weights. The obtained copolymers were characterized by Fourier transform infrared spectroscopy ...
Graft Copolymers for Blend Compatibilization: Mathematical Modeling of the Grafting Process
(Wiley VCH Verlag, 2012-10)
The grafting of PE onto PS through a Friedel-Crafts reaction, which results in a mixture of PE-g-PS copolymer, unmodified PE, and modified PS, is investigated. The copolymer may be suitable for compatibilization of immiscible ...
SYNTHESIS OF FLAX-G-COPOLYMERS UNDER PRESSURE FOR USE IN PHENOLIC COMPOSITES AS REINFORCEMENT
(Sociedad Chilena de Química, 2009)
Self-assembly in aqueous solution of amphiphilic graft copolymers from oxidized carboxymethylcellulose
(Elsevier B.V., 2015-06-25)
A series of oxidized carboxymethylcellulose-graft-poly(ethylene glycol)-dodecylamine (0CMC-g-PEG-DDA) was prepared by using an appositely prepared PEG with terminal amino groups and different amounts of DDA. The nanoaggregates ...
Thermoresponsive hydrogels from alginate-based graft copolymers
(Elsevier, 2014-10-02)
Three samples of sodium alginate grafted by amino-terminated PNIPAM (low and high molecular weight poly(N-isopropylacrylamide)) and a random P(NIPAM-co-NtBAM) (NtBAM: N-tertiary butyl acrylamide) copolymer, were synthesized ...
Fractured orbital wall reconstruction with an auricular cartilage graft or absorbable polyacid copolymer
(2011-07-01)
Objective: The objective of the study was to compare the functional and aesthetic results of fractured orbital wall reconstruction with an auricular cartilage graft or absorbable polyacid copolymer. Materials and Methods: ...
Modification of propylene-α-olefin copolymers by maleic anhydride grafting and blending
(Taylor & Francis Ltd, 2019-04-15)
Five commercial random propylene-α-olefin copolymers were functionalized with maleic anhydride by reactive mixing. Materials and blends of the original polymers with the grafted ones were characterized by IR, SEC, rheology, ...
