The compositions are mixtures containing dicyclopentadiene (meth) acrylate and (meth) acrylates such as the mono and di (meth) acrylates of tri, and tetracyclopentadiene and a mixture of the copolymers of (meth) acrylic acid with adducts of cyclopentadiene with isoprene and/or piperylene and a mixture of poly (meth) acrylates having the repeating unit ##STR1## Where R.sup.1 is hydrogen or ##STR2## R.sup.2 is CH.sub.2 .dbd.CZ--C(O)--O-- Z is H, or methyln is 0, 1 or 2 andm is 0 or 1 and when m is 0 there isa double bond present.The compositions are useful to make cross-linkable blends with unsaturated resins or monomers and to make laminates.

Abstract: This invention is directed to compositions useful as ionomeric hot melt pressure sensitive adhesive compositions. These compositions comprise a polymer containing carboxylic acid, a miscible metal salt, and an o-methoxy-substituted aryl acid. These compositions display low melt viscosity, simplifyingapplication, as well as improved adhesive properties, especially shear resistance.

Abstract: Brominated cycloaliphatic (meth) acrylate compositions are prepared by the reaction of bromine at a temperature in the range from -30.degree. C. to 50.degree. C. with compositions made by reacting (meth) acrylic acid with dicyclopentadiene compositions in the presence of a Friedel-Crafts catalyst such as BF.sub.3.The brominated compositions are useful to make copolymers which find use as metal coatings, laminates, ultraviolet light curable coatings and the like.

Abstract: A continuous process for producing rubber-modified methyl methacrylate syrups which comprises continuously supplying a material liquor comprising 1 to 20 parts by weight of a rubbery polymer dissolved in 100 parts by weight of a monomer comprising 60 to 100% by weight of methyl methacrylate, and a radical-polymerization initiator to the first reaction zone, continuously polymerizing at such a stationary conversion that the rubber polymer is dispersed in the form of particles form while maintaining the temperature and residence time in the zone so that a steady state is achieved in the zone and the steady-state concentration of the initiator in the zone is 1/2 to 1/1,000 time as much as the concentration of initiator supplied, continuously taking out the resulting reaction mixture from the zone, and passing it through the second reaction zone having a volume of 0 to 5 times as much as that of the first reaction zone, to obtain a stable syrup comprising a disperse phase and a continuous phase, the former phase

Abstract: Coating compositions which are free of volatile organic solvents and curable under the action of heat or radiation without undesirable evaporation of organic solvents, prepared by reacting a copolymer resin of a cyclopentadiene type compound such as dicyclopentadiene and maleic anhydride, with at least one compound represented by the formula ##STR1## or the like wherein X is H or --CH.sub.3 and R is --CH.sub.2 CH.sub.2 OH or the like to produce a resin which is then dissolved in a reactive solvent such as a (meth)acrylate type monomer or ammonia water; and a process for preparing the coating compositions.

Abstract: Graft copolymers comprising a crosslinked, saturated, elastomeric grafting base and a hard shell are prepared by incorporating thermolabile comonomers, as copolymerized units, into the grafting base during the preparation of the latter, in particular at a conversion of from 50 to 90%. During the subsequent grafting of the shell, the conditions used are such that the thermolabile comonomers incorporated as copolymerized units into the grafting base decompose into free radicals. This gives graft copolymers having improved mechanical properties, which copolymers also prove advantageous for the preparation of mixtures with other thermoplastics compatible with the graft copolymers.

Abstract: The present invention provides a method for producing curable resin which comprises reacting acrylic acid and/or methacrylic acid [which is hereinafter cited as (metha-) acrylic acid] with hydroxyl group-containing resin (I) obtained by reacting a five-member cyclic compound having an unsaturated conjugated double bond represented by the general formula (A) given below; ##STR1## (WHEREIN R is an organic residue having from 1 to 3 carbon atoms; m and n are integers and are in the relation of m+n=6) or the Diels-Alder addition product thereof (A) and a compound (B) having both reactive carbon-carbon double bond or bonds and towo or more hydroxyl groups within one and the same molecule thereof. In accordance with the present invention, curable coating composition comprising said curable resin can also be obtained. The resin of this invention can be very quickly cured by the exposure to heat or radiation.
