Title: | Synthesis and Structure: Property Relations of Latexes Comprising Graft Copolymers between Telechelic Polybutadiene and Dodecyl Methacrylate | Contributor(s): | Pham, Binh T T (author); Gilbert, Robert G (author); Fellows, Christopher (author) | Publication Date: | 2004 | DOI: | 10.1071/CH04030 | Handle Link: | https://hdl.handle.net/1959.11/5747 | Abstract: | Latexes comprising novel copolymers were formed by second-stage emulsion polymerization of dodecyl methacrylate (DMA) onto a hydroxylated polybutadiene-based polyurethane prepolymer (PUD) as seed latex, with persulfate initiator. Morphology data from TEM imaging (including chemical fixation ultra-microtoming), glass transition temperature, dynamic mechanical analysis, and other mechanical-property data were all consistent with a system showing extensive grafting and compatibilization between the different polymeric components. Water adsorption and AFM measurements showed that samples with poorer film-forming properties had higher water sensitivity, greater mixing of the polymer phases, and poorer mechanical properties. These properties were related to a phase-inversion phenomenon occurring above a critical dodecyl methacrylate/prepolymer ratio. The compatibilization of the PUD and poly(DMA) given by these modifications resulted in a product with increased tackiness, although with a higher water sensitivity. | Publication Type: | Journal Article | Source of Publication: | Australian Journal of Chemistry, 57(8), p. 765-777 | Publisher: | CSIRO Publishing | Place of Publication: | Australia | ISSN: | 1445-0038 0004-9425 |
