Plastic composition for plastic facing sheets and adhesives

Plastic compositions for the production of plastic facing sheets should be sufficiently elastic and reliably bondable, and in addition fire prevention demands are made. It has been found that plastic compositions which allow both the production of a plastic facing sheet and the preparation of an adhesive for these facings can be produced on a vinyl basis with addition of plasticisers, the necessary elasticity and flame resistance being achieved by employing as plasticisers, chlorinated alkyl compounds and/or organic phosphoric acid esters. The structure of the facings is achieved by structure-forming additives, added fibres preventing the facings cracking when bent around tight corners.

HEAT-RESISTANT ADHESIVE

Pressure sensitive adhesives comprising ethylene vinyl acetate dioctyl maleate terpolymers

Permanently tacky pressure sensitive adhesives comprise terpolymers consisting essentially of 35-50% by weight of a vinyl ester of an alkanoic acid, 15-30% by weight ethylene and 35-50% by weight of di-2-ethylhexyl maleate or di-n-octyl maleate or a corresponding fumerate.

Flocking adhesives based on eva-maleate copolymers

Flocking adhesives are prepared from an aqueous emulsion prepared by the emulsion polymerization of a vinyl ester of an alkanoic acid interpolymerized with: 10 to 30% by weight of ethylene; 15 to 40% by weight of a C 4 -C 10 dialkyl maleate; 1 to 5% by weight of an N-methylol containing copolymerizable monomer; 0 to 4% by weight of an olefinically unsaturated carboxylic acid; and 0 to 1% by weight of a polyethylenically unsaturated comonomer.

Laminating construction adhesive compositions with improved performance

Aqueous laminating construction adhesive compositions incorporating a one-part adhesive copolymer, the copolymer being a vinyl ester/acrylic copolymer containing from about 0.1% to about 20%, by weight based on copolymer weight, of a copolymerized polar monomer, the copolymer having a Tg from about 10° C. to about -35 C. are provided which exhibit a good balance of high temperature and ambient temperature adhesion performance in a one-part adhesive composition.

Water borne pressure sensitive vinyl acetate/ethylene adhesive compositions

The present invention is directed to improved vinyl acetate ethylene pressure sensitive adhesive emulsion polymers. The improvement in the aqueous based, emulsion polymerized pressure sensitive adhesives resides in: a high ethylene content copolymer having a Tg of from −25 to −70° C.; a tensile storage modulus measured at one hertz and at a temperature of −20° C. embraced by the points on a plot of storage modulus and temperature of from 1 times 10 6 and the points 4 times 10 9 dynes/cm 2 and less that 1 times 10 7 dynes/cm 2 measured at 50° C.
