The Application of Titanates in PVC was the title of my Vinyltec 2004 technical paper having 64-pages with 43-Tables, 46-Figures, and 48-References that captured 3-decades of PVC developments and their application methodologies. The fundamental teachings of the 2004 paper are the platform for significant vinyl developments in this 2020 paper covering the ensuing 16-year period. For example, it will be shown that 0.2% of a cycloheteroatom zirconate by weight of a clear recycled rigid PVC can double extrudate production at an 85°F lower temperature due to the catalysis effect of the zirconate on the PVC polymer melt. It will be demonstrated that plasticizer levels can be reduced up to 18% by use of 0.2phr titanate without loss of flexibility or stress/strain properties. It will be shown that independent of any coupling mechanism, PVC can be repolymerized, copolymerized or depolymerized allowing for many polymer blending, alloying, recycling and sustainability scenarios. Monoalkoxy or Neoalkoxy Titanate in combination with Al2SiO5 mixed metal catalyst in Powder & Pellet forms for In Situ Macromolecular Repolymerization and Copolymerization in the melt – i.e. Polymer Compatibilization AND The Neoalkoxy Titanate proton coordinates with inorganic fillers and organic particulates and pigments to couple/compatibilize the dissimilar interfaces at the nano-atomic level thus reducing the need for expensive sorting of materials in Recycled Plastics. It will be shown that subject organometallics are different than silanes and can functionalize non-silane reactive inorganic/organic particulate in situ in the PVC melt. Effects on ordinary Portland cement will show a 31% reduction in the water to cement ratio while opening up the cement interface to polymer compatibilization. Heteroatom phosphorus-titanium monomolecular char will be shown to enhance PVC flame retardance. ACS CAS Abstracts will be provided demonstrating new and novel PVC compositions containing nano-CaCO3 to graphene. For example: Synthetic PVC leather cloth combining nano-filler and titanate and silane chemistry for fabric used in furniture and sports shoes with resistance to tearing for 3 to 5 years; NBR/PVC blended materials have high ozone resistance, weather resistance, ageing resistance, tensile strength, stress at definite elongation, tear resistance, heat resistance, fire resistance, oil resistance, fuel resistance, chemical resistance, drawability and storage stability. It will also be suggested that new data points to a means to control the temperature of the release of CO2 gas allowing NaHCO3 to be a safe chemical blowing agent substitute for SVHC Azodicarbonamide.
