0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Tertiary carbonic acid can be converted into vinyl ester monomer by reaction with acetylene. Vinyl tere carbonate is a very hydrophobic monomer with a-carbon tertiary carbon structure. Their main use is as a hydrophobic comonomer in the polymerization of vinyl and acrylic acid. The alkyl tertiary carbonate groups of these monomers are resistant to degradation under alkaline conditions because there is no hydrogen on the α-carbon atom. A branched tertiary carbon structure with a large volume and hydrophobic hydrocarbon groups can provide a tertiary ethylene carbonate monomer with high hydrophobicity and low surface tension. In addition, these tertiary ethylene carbonates exhibit strong hydrolysis resistance and will not degrade under the influence of ultraviolet light. therefore,Acrylic emulsionIt can be modified with tertiary ethylene carbonate.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; Ethylene terecarbonate is easily copolymerized with various other monomers through vinyl ester. In this way, the copolymer can be given specific properties of this monomer. Vinyl terecarbonate improves the performance of vinyl acetate and acrylic emulsions, and can significantly improve the key properties of two types of polymer systems, such as water resistance and alkali resistance.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; polymers based on tertiary ethylene carbonate exhibited the required hardness and flexibility, hydrophobicity and chemical resistance of the polymer The balance between them is good for preparing various latex coatings. The obtained coating has better water resistance, ultraviolet light resistance and alkali resistance, and therefore has better outdoor durability. Ethylene terecarbonate has been successfully used to prepare acrylic emulsions. Used as a paint base for architectural coatings, these vinyl copolymer latexes provide improved scrub resistance and outdoor durability.
0010010 nbsp; 0010010 nbsp; 0010010 nbsp; The hydrophobicity and hydrolysis resistance and UV light degradation properties conferred by the tertiary ethylene carbonate monomer make them particularly suitable for production Higher latex, especially when copolymerized with acrylic and methacrylic monomers. Acrylic emulsions modified with tertiary ethylene carbonate monomers can be formulated into protective coatings, such as anticorrosive coatings, waterproofing systems, wood coatings, elastomeric roof coatings and adhesive applications such as pressure sensitive adhesives (PSA).
