Films useful as optical reflectors are prepared by coating a sheet of polyethylene terephthalate or other thermoplastic with acrylic polymer, white pigment, and optionally other additives such as impact modifiers, matting agents and UV stabilizers.

A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post vulcanization composition. The pre-vulcanization composition comprises soluble sulfur with high S.sub.8 ring structure that is catalytically broken by a zinc dithiocarbamate. Surfactants present in the pre-vulcanization composition wets synthetic polyisoprene particles and permeates small sized sulfur and accelerator molecules into the interior of these particles thereby pre-vulcanizing the particles. The degree of pre-vulcanization is verified by isopropanol index test. The latex emulsion has post-vulcanization composition with accelerators that crosslink inter-particle region during post vulcanization cure cycle. The dipped synthetic polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds in TEM and zinc segregation at the boundaries or original particles by electron microprobe analysis. The films exhibit high tensile strength, tensile modulus, tear strength, burst pressure and burst volume.

An interlayer film for a laminated glass includes a thermoplastic resin and a plasticizer. The ratio of a high molecular weight component with an absolute molecular weight of 1000000 or more in the thermoplastic resin is 7.4% or higher, or the ratio of a high molecular weight component with a polystyrene-equivalent molecular weight of 1000000 or more in the thermoplastic resin is 9% or higher. A first multilayer interlayer film for a laminated glass includes an interlayer film for a laminated glass and an interlayer film for a laminated glass that contains a thermoplastic resin and a plasticizer, and is laminated on one face of the interlayer film for a laminated glass.

The invention relates to a multi-layer structure having at least one inner layer containing an alloy of a biopolymer and an acrylic polymer and at least one outer layer containing a thermoplastic or thermoset polar polymer matrix. The combination of outer polar layer and an inner biopolymer/acrylic layer provides improved properties, such as improved adhesion, and improved mechanical properties. The multi-layer structure may be in the form of a sheet, a film, a tube or pipe, or a profile, and could be used by itself or as a cap-layer over a substrate.

The present invention also provides a heat shrinkable label including the heat shrinkable multilayer film. Provided is a heat shrinkable multilayer film including: front and back layers each containing a polyester resin; an interlayer containing a polystyrene resin; and adhesive layers, wherein the front and back layers and the interlayer are stacked with the adhesive layers interposed therebetween, and the adhesive layers each contain a polyester resin having a glass transition temperature of 77? C. or lower.

The present invention provides an elastomeric composition for making elastomeric articles having at least one layer, such as but not limited to condoms, which have a deformation stress or modulus below about 1.5 MPa at 500% extension, comprising at least one polymeric material, at least one plasticizer and optionally at least one coating. The elastomeric articles also have unique tactile and tensile properties, such as conformability and low radius of curvature.
