TAILORABLE SURFACE TOPOLOGY FOR ANTIFOULING COATINGS
Embodiments are directed to a method of making an antifouling and bactericidal coating with tailorable surface topology. The method includes depositing a layer of branched polyethyleneimine (BPEI) and diamino-functionalized poly(propylene oxide) (PPO) in a mixture of water and organic solvent on a substrate to form a layer of BPEI/PPO. The method includes depositing a layer of glyoxal in a water-containing solution on the layer of BPEI/PPO. The method further includes curing the layer of BPEI/PPO and layer of glyoxal to form a homogenous, glyoxal crosslinked BPEI/PPO coating, where the curing induces local precipitation and alteration of the glyoxal crosslinked BPEI/PPO coating to provide a textured surface.

The mould comprises a base plate and a plurality of forming areas, wherein each forming area comprises a cavity in the base plate and a forming sleeve placed in the cavity. Each forming area further comprises first heat means for heating or keeping heated the forming sleeve relative to the base plate, such that the temperature of the part of the film which lies against the forming sleeve during cooling remains above a glass temperature of the plastic long enough to obtain a product with an at least partially crystalline structure.
PREFORM NECK CRYSTALLIZATION METHOD
A wide-neck synthetic resin container has a neck, a body and a bottom. A top side of the neck is sealed by a cap. The neck includes a neck tubular section, an engagement section protruding outward therefrom and engaging the cap, and a flange protruding outward at the top side. The flange protrudes less than the engagement section. The neck's top side includes a first top side formed by the neck tubular section, and a second top side formed by the flange that is the same height level with the first top side and increases an area of the top side. The neck tubular section has a uniform thickness at an area immediately below the flange and an area where the engagement section is formed. A thickness of the flange is smaller than that of the neck tubular section, and the neck has been crystallized.
Highly modified polyesters for containers
A polyester resin for use in a process in which, during an expansion step, an incompressible fluid is injected through an opening of a preform, formed of the polyester resin, to form a container. The polyester resin includes a crystallizable polyester polymer wherein the polyester polymer is comprised of acid moieties and glycol moieties, with at least 85% of the total moles of acid moieties being terephthalate derived from terephthalic acid or its dimethyl ester and at least 85% of the total moles of glycol moieties derived from ethylene glycol.
