ACRYLIC RUBBER FOR THERMOPLASTIC MATERIAL WITH GOOD LOW TEMPERATURE IMPACT STRENGTH - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240239936 titled 'ACRYLIC RUBBER FOR THERMOPLASTIC MATERIAL WITH GOOD LOW TEMPERATURE IMPACT STRENGTH
The patent application describes a graft copolymer composed of a graft base and a graft shell, which can be used in automotive and construction applications.
- The graft copolymer consists of a graft base (b1) made up of 80 to 98.9 wt.% of a C1 to C4 alkyl acrylate, 1 to 19.9 wt.% of a C9 to C22 alkyl(meth)acrylate, and 0.1 to 10 wt.% of a bi- or polyfunctional crosslinking monomer.
- The graft shell (b2) is obtained in the presence of the graft base through emulsion polymerization of 50 to 95 wt.% vinylaromatic monomer and 5 to 50 wt.% vinylcyan monomer.
- The resulting graft copolymer can be used in thermoplastic molding compositions for various applications.
Potential Applications: - Automotive parts such as bumpers, interior trim, and exterior panels - Construction materials like roofing membranes, sealants, and adhesives
Problems Solved: - Enhanced mechanical properties and durability in automotive and construction applications - Improved weather resistance and chemical stability
Benefits: - Increased strength and impact resistance - Better weatherability and long-term performance - Versatile applications in different industries
Commercial Applications: - Potential for use in manufacturing automotive components and construction materials - Market implications in the automotive and construction industries
Questions about the technology: 1. How does the composition of the graft copolymer contribute to its mechanical properties and durability? 2. What specific advantages does the graft copolymer offer over traditional materials in automotive and construction applications?
