Abstract: An article comprises a laminate with a layer comprising a first latex composition containing a cross-linker component selected from sulfur, organic peroxide, vulcanizing activators, and vulcanizing accelerator; and a second layer comprising a second latex composition free of the cross-linker component. The laminate is formed by dipping a mold into the first latex composition then into the second latex composition forming a laminated film, then curing the laminated film by heating to a temperature between 90° C. to 140° C. Lastly, the laminated film is removed from the mold via inversion such that the second layer is inwards and the first layer is outwards.

Abstract: Branched block copolymers, derived from alkenyl aromatic hydrocarbon-1,3-diene monomer system, and branched polyisoprene homopolymers, derived from isoprene, are obtained by polymerization in the presence of an anionic initiator; at a temperature from 0° C. to 100° C.; followed by coupling with a multifunctional coupling agent of formula (R1O)3Si—Y—Si(OR2)3, wherein R1 and R2 are independently C1-C6 alkyl groups; and Y is a C2-C8 alkylene group. The polymers thus obtained can be used in many applications, including rubber cements having high solids content and low zero shear viscosities, and for producing aqueous latices therefrom.

Abstract: The present invention relates to a method including a rubber-like film-based article of which at least a portion is firmly fixed to a substrate. The method includes providing a film-based article made of a non-crosslinked thermoplastic rubber, contacting at least a portion of the film-based article with a substrate so as to form a contact area between the film-based article and the substrate, and heat sealing at least a portion of the contact area at a temperature of 190 to 250° C. for at least 1 second.

Abstract: A transparent laminate having a haze of less than 10% measured according to ASTM D1003-13, wherein the laminate comprises: i) at least a first substrate, ii) at least a second substrate and iii) an adhesive film between the first and second substrate, wherein the adhesive film is a cured, transparent rubber film obtained by curing an adhesive composition comprising: a) at least 80% by weight of at least one polyisoprene rubber, b) 0.5 to 15% by weight of at least one organic compound comprising at least two vinyl groups and c) 0.01 to 10% by weight of at least one peroxide compound.
