[0128] Preparation of Elastomeric Film-Forming Compositions

[0129] Compositions for producing elastomeric films can be prepared by mixing components (a), (b) and (c) and any optional additional components in a liquid such as water. Methods may include pre-preparing individual components at specific concentrations (total solids), diluting the components, if necessary, combining, and making any further dilutions as necessary to achieve the final total solids set for the composition.

[0130] Suitable additives or other components as described above may be included in the composition and may be added to the combination of components (a) and (b) prior to the addition of the crosslinker (c), or to both In a mixture of (a), (b) and (c).

[0131] Typically, the powder components of the composition are combined and ground using suitable grinding equipment to reduce the particle size to a suitable range. Preferably, the average particle size is less than 5 microns. A uniform parti...

preparation Embodiment 6 to 9

[0217] The formulations having the compositions shown in Tables 2 and 3 were based on different relative amounts of polychloroprene and carboxylated butadiene-based elastomer. In Examples 1 to 5, there were variations in the amount of crosslinker and other components present in the composition. Examples 6 to 9 were then prepared as follows: Based on fixed amounts of crosslinker and other components (based on the amounts used in Example 5), only the relative amounts of polychloroprene and carboxylated butadiene-based elastomer occurred Variety. When the results of Examples 6 to 9 and Example 5 are considered together, they show a trend when varying the relative amount of elastomer from 5% to 27%.

[0218] Gloves were prepared from the compositions following the general procedure shown above.

Abstract

The invention relates to an elastomeric film-forming composition (a) a carboxylated butadiene-based elastomer, (b) polychlorobutadiene in an amount of less than 30% by weight of the polymer content ofthe composition, and (c) one or more cross-linking agents. The invention also relates to dipped articles, gloves, methods of manufacture and uses involving the composition.

Description

technical field [0001] The present invention relates to elastomeric film-forming compositions useful in the manufacture of dipped articles, such as gloves, as well as articles made from the elastomeric film-forming compositions and methods of forming articles from the compositions. Background technique [0002] Articles such as gloves made of natural (polyisoprene) rubber have a good feel and comfort. However, natural (polyisoprene) rubber is associated with potential allergens that cause type I allergy. In view of this allergic property, natural (polyisoprene) rubber is generally unsuitable for use in the manufacture of articles such as rubber gloves due to its adverse effects on the wearer. [0003] Other compositions that can be used to form gloves and other similar articles are based on synthetic materials such as nitrile rubber, polyisoprene, styrene-butadiene rubber, butyl rubber, and vinyl polymers. The production of gloves using synthetic materials has increased si...
