High performance bituminous mixtures that are useful for the road paving and roofing industries comprise mineral aggregates coated with a thermoplastic polymer composition. Because of their high performance properties, the absence of any aggressive and toxic adhesion promoters and the possibility of using recovered or recycled thermoplastic polymers to form the coating or 'membrane,' the bituminous mixtures described herein provide an excellent environmentally friendly solution for pavement construction and roofing industries.

Bituminous mixtures comprising thermoplastic polymer membranes

Blends of acrylic copolymer and polyester urethane provide resin suitable for use as enamel coatings which, when cured, exhibit both hardness and flexibility.

Flexible coating compositions

Acrylic polymers prepared from hydroxy alkyl esters of acrylic or methacrylic acid, glycidic monomer and ethylenically unsaturated monomer, as well as enamels based on mixtures of such polymers and diglycidyl esters of dibasic acids.

Internally crosslinkable acrylic polymers and diglycidyl esters of

Polyesters with oxazoline units, especially useful as additives to promote adhesion in crosslinked enamels.
