  • Patent number: 11895957
    Abstract: Biodegradable planter pots constructed from starch and an outer silicon layer. The starch provides a biodegradable and/or compostable characteristic to the pot, allowing it to be broken down into the soil after the pot has been planted. The outer silicon layer provides durability to the pots, allowing them to retain their shape for an additional period of time and withstand handling, while also retaining the biodegradable characteristics of the pots. Advantageously, the pots allow seedlings and seeds to be directly deposited into the soil, while also providing structure to the plant for the initial growth period. Advantageously, the pots provide a stable structural support that is hardy and/or water-resistant but can also being broken down as the plant grows.

  • Patent number: 6492462
    Abstract: The rheological properties of a crosslinkable resin system are modified by the presence of a side chain crystalline (SCC) polymer (or a similar crystalline polymer which melts over a narrow temperature range). The polymer dissolves in the curable system at temperatures above the melting point of the crystalline polymer (Tp), but when the system is then cooled to a temperature below Tp, at least partially forms a separate phase in the curable system. Below Tp, this separate phase substantially increases the viscosity of the curable system (i.e. makes it thicker than the same system without the crystalline polymer). This is particularly valuable for sheet molding composites (SMCs) in which the increase in viscosity makes the composites less tacky, and for dry film resists (DFRs). Above Tp, the curable system containing the dissolved crystalline polymer has a viscosity which is substantially less than its viscosity below Tp.

  • Patent number: 6160038
    Abstract: A method for dispersing solid forms of additives in polymers involves adding dispersions or solutions of additive(s) to a solution of polymer in a tubular mixer (preferably in the presence of a stationary mixer). The mixer leads to a steam precipitation step wherein all fluid ingredients in the mixture are volatilized leaving the solid additive and resin in the desired ratio. This results in a uniform dispersion of the additives in the polymer matrix. As a result of the high dispersion, physical properties of a thermoplastic resin, to which the polymer matrix has been added are preserved. In one illustration, PTFE as a drip inhibitor additive, is added to polycarbonate to obtain a highly dispersed PTFE concentrate of improved drip-inhibition without loss of mechanical properties when added to a thermoplastic molding resin.

  • Patent number: 5969046
    Abstract: A method for reacting a methylene-containing component such as an acrylic polymer prepared from acetoacetoxyalkyl (meth)acrylate and an alkene-containing component such as a polyfumarate, polymaleate, a polyester containing both fumarate and maleate groups or a polyacrylate comprises the reaction of a tertiary amine such as triethylene diamine and an epoxide such as a glycidyl-functional (meth)acrylic polymer in the presence of the methylene-containing component and alkene-containing component. The tertiary amine can be incorporated into the alkene-containing component such as the reaction of an unsaturated polyester with a compound having both tertiary amine and primary or secondary amine groups. The tertiary amine can be incorporated into the methylene-containing component such as an acrylic polymer derived from a tertiary amino-functional monmer and acetoacetoxyalkyl (meth)acrylate.

  • Patent number: 5693714
    Abstract: Rubber particles, to be used as fillers or extenders for various composite polymer systems, are chlorinated by a gas-solid phase reaction with a chlorine-containing gas. A composite polymer containing the chlorinated rubber fillers or extenders exhibits a higher flexural modulus than if prepared using an unchlorinated rubber filler or extender. Chlorination of the rubber particles is carried out by contacting the finely divided rubber particles with a chlorine-containing gas comprising at least about 5 volume percent chlorine. Advantageously, the chlorine can be diluted with air, nitrogen or other essentially inert gases and may contain minor amounts of fluorine. Improved performance is obtained with nitrogen dilution of the chlorine gas over air dilution. Improved polymer composite systems having higher flexural modulus result from the use of the chlorinated rubber particles as fillers instead of unchlorinated rubber particles.
