摘要:
The present invention relates to compositions formed by mixing herbicides with polymers. The herbicide acts, as a primary plasticizer, to plasticize the resin and exudes from the resin/herbicide composition over a period of time. The polymer/herbicide composition can be in the form of an aqueous latex, suitable for coating of a substrate, can be in the form of a plasticised resin capable of being formed into articles of manufacture (eg. lawn edging), or can be in the form of an extrudable plasticized latex which can be directly applied to the soil locus (e.g. to a trench) and allowed to stand. Control over the amount and type of surfactant used in the manufacture of the polymer with which the herbicide is to be mixed can influence the rate and amount of herbicide that exudes from the composition.

Triazine terminated oligomers having a plurality of tetramethyl piperidyl moieties are useful as polymer additives to import resistance to degradation when exposed to actinic radiation.
摘要:
Polyurethane/polyurea foams are made by reacting an organic polyisocyanate with resins containing imino/enamino-functional groups in the presence of blowing agents. Control of foam properties is offered by selecting imino/enamino-functional groups which decompose with water at the temperature of the reaction to produce volatile gases.
摘要:
Isocyanate-reactive prepolymers having imino/enamine functionality are made by reacting an isocyanate-terminated urethane prepolymer with compounds having imine or enamine functionality. These prepolymers are useful in reaction injection molding systems as isocyanate-reactive ingredients.
