    Abstract: The present invention provides a method for recovering oil from a subterranean reservoir using waterflooding, wherein the flooding fluid used in the waterflooding process comprises water and one or more ionic polyvinyl alcohol copolymers. The use of one or more ionic polyvinyl alcohol copolymers is expected to increase the recovery of oil by improving both the oil/water mobility ratio and the sweep efficiency in reservoirs with a high degree of heterogeneity.

    Abstract: A phase transition golf ball comprises a phase transition material. The phase transition material may optionally include a microwave susceptor or an induction susceptor. The phase transition material preferably comprises an ethylene acid copolymer, or an ionomer of an ethylene acid copolymer. The performance of the phase transition golf ball, for example its hardness or compression, is adjusted by inducing a complete or partial phase transition in the phase transition material. The extent of the adjustment in performance is correlated with the extent of the phase transition. Preferably, the phase transition is reversible and repeatable and takes place at temperatures that might be achieved through the use of common household appliances. Also preferably, the phase transition material returns to its original state over an extended period, for example hours or days.

    Abstract: A method is provided for cleaning the interior of polymer processing equipment having a resin composition retained therein, wherein a contaminant material is adhered to at least a portion of the interior surface of the polymer processing equipment. The method comprises the steps of: charging the polymer processing equipment having a residual polymer composition retained in the interior thereof with a purging composition comprising 45-94 weight % of starch; 0.05 to 20 weight % of water; and (3) 5 to 45 weight % of polyol plasticizer, wherein the weight percentages of starch, water and polyol plasticizer are based on the total weight of starch, water and polyol plasticizer; operating the polymer processing equipment to i) convey the purging composition through the polymer processing equipment, thereby removing and withdrawing substantially all of the residual polymer composition from the polymer processing equipment and causing a portion of the purging composition to be retained as a residual purging composition within the interior of the polymer processing equipment; and ii) remove at least a portion of the contaminant material that is adhered to an interior surface of the polymer processing equipment; and removing the portion of the purging composition retained as a residual purging composition from within the interior of the polymer processing equipment.
