Editor's Notes
- Indication of relative reaction rates in free radical polymerization If the molecules 1 and 2 differ widely in polarity, then the exponent in the rate equation will be large and therefore the exponential will be small
- Relative to styrene our monomers are less volatile which has lead to use in numerous applications Because of the alkyl groups on the aromatic structure water is less soluble. Additionally we have seen water barrier and reduced water absorption of polymers based on Deltech monomers
- In many thermoset systems we have seen lower shrinkage on cure similar to the lower shrinkage of homopolymerization Heat of polymerization relative to styrene is also lower with respect to styrene; and between this and lower shrinkage we have seen many thermoset systems have reduce rates of imperfections. Higher TG’s of PMS and VT lead to improve properties in coatings, thermoplastics and thermoset systems. The solubility parameter is an indication of improved solubility of our materials in solvents which can be beneficial in high solids coatings or absorbtion of organics
- Based on the uses of VT, PMS and TBS and review of patents demonstrating the use of our monomers we have seen common beneficial properties that our monomers provide polymers, resins and reative systems which transends polymer type. Low vapor pressure of VT relative to styrene reduces worker exposure. Also VT, PMS and TBS are not listed on HAPS whereas styrene is. Because of the additional methyl group attached to the aromatic part of the VT structure it improves it’s solubility as a monomer and in resins, and even more effective in parraffinic solvents like mineral spirits achieving high solids coatings demonstrated in alkyd and acrylic resins. Systems based on using VT as a reactive diluent have excellent electrical insulating properties Because of the methyl group on the aromatic it provides excellent hydrophobicity demonstrated in coating resins and UPR composites Coatings based on VT have good resistance to caustic and acids and cane be applied directly to fresh cement and plaster The elevated Tg’s of resins based on our polymers leads to higher hardness coatings Coating resins based on VT dry very quickly and their good solvent release makes VT excellent for dryfall applications As a reactive diluent VT keeps system viscosities low in UPR composite systems, insulating varnishes and coating systems. Because of the lower cure exotherm compared to styrene, VT based systems reduce composite defects Lower shrinkage of VT (as well aPMS and TBS) provide better dimensional stability.
- Because of the additional methyl group attached to the aromatic part of the PMS structure it improves it’s solubility as a monomer and in resins, and even more effective in parraffinic solvents like mineral spirits. This high solubility leads to high solids coatings. Because of the methyl group on the aromatic it provides excellent hydrophobicity demonstrated in coating resins (like acrylic based coatings) PMS blocks in a polymer can readily be functionalized homogeneously providing distinct properties to a resin including barrier properties, UV/EB crosslinking capability, or improved compatibility with other resins or solvents. Films of copolymers based on PMS demonstrate excellent clarity, light transmission and ability to polarize light. The alignment of PMS blocks can create hardblock structures with amorphous structures leading to hydrogen bond crosslinking in a thermoplastic (Kurraray’s Septon) The compatibility of PMS with flame retardants like polyphosphates leads to intumescent coatings.
- Because of the low vapor pressure (as well as not being listed on HAPS) TBS is used in reactive resin systems where limited worker exposure is required (like mines) Use of TBS can lead to high solids coatings of 85%. Additionally TBS polymers included in crosslinked copolymer beads can be used to absorb organic spills. Becausse of the large t-butyl group TBS can be used to provide high water barrier or corrosion reistant properties in a resin or composite. Due to molecular alignment and hydrogen bonding TBS homopolymer achieves high Tg. It has been used to control adhesive tackifier softening temperature as well as compatibility and heat stability in a hot melt system. TBS like PMS can provide films with good optical properties.
