Resin composition for cement

Concrete-protective material

A resin composition comprising a copolymer (A) having carbon-carbon unsaturated bonds in its side chains, particularly that obtained by reacting a copolymer of alkyl (meth)arylate (0-50 mole %), hydroxy (meth)acrylate (10-50 mole %) and ethylenic unsaturated monomer (0 to 90 mole %) with an unsaturated carboxylic acid or an anhydride thereof, and a monomer (B) copolymerizable with (A) is suitable for producing a laminate for electrical use.

Resin composition and electrical laminate obtained therefrom

A flame retardant electrical laminate prepared by impregnating a base material with a halogen-containing unsaturated polyester resin which is prepared by dissolving a halogen-containing unsaturated polyester into a polymerizable monomer; and then curing the halogen-containing unsaturated polyester resin; wherein the halogen-containing unsaturated polyester has a molecular weight per 1 mole of unsaturated group of 350 to 1,000, and the cured halogen-containing unsaturated polyester resin has a glass transition temperature of 30.degree. to 90.degree. C. Such electrical laminates not only have excellent flame redardancy but also excellent puching quality at wide temperature range including room temperature.

Flame retardant electrical laminate

A resin composition obtained by adding maleic anhydride to an unsaturated polyester resin composition comprising (I) an unsaturated polyester, (II) a styrene monomer, and (III) at least one polymerizable unsaturated compound, in limited amounts is low in viscosity, excellent in transparency and adhesiveness, able to prevent the generation of surface defects, and thus suitable for treating cathode-ray tubes.

Process for using unsaturated polyester resin composition for treating
