Development of a bio-based silyl-terminated prepolymer from renewable resource, allowing obtaining adhesive with increased moisture and UV resistance, reduced toxicology risks and replaced part of synthetic polymer.
popup.description2
The object of research is one-component prepolymer systems based on polyester with silyl end groups for the creation of a weatherproof sealant.
The aim of the research is to develop a biobased formopolymer with silyl end groups from renewable resources, which allows to obtain a sealant with increased moisture resistance, UV resistance and reduced toxicological risks with the replacement of a part of synthetic polymer. The research methods used were optical microscopy, shear method, peeling method, Vick's softening point method, and microbiological method. The adhesion ability of one-component prepolymer systems based on polyester with silyl end groups to steel and glass surfaces was investigated. The dependence of the adhesive properties on the structural composition of the prepolymer system was revealed. The influence of the nature and content of cardanol on the adhesive ability of the studied prepolymers was investigated. The microbiological and thermogravimetric analysis of polymer sealants was carried out. The optimal temperature conditions for the operation of the studied one-component sealants were determined. Areas of application: M 72.19 Research and experimental development in the field of other natural and technical sciences.
