摘要:
This invention is directed to a process of forming composites comprising reinforcing fibers dispersed in a thermoplastic polymer matrix, said process comprising the steps of coating a reinforcing fiber with a curable resin and an initiator for the curing of the resin and for the polymerization of monomer of said polymer; curing said resin to form cured resin coated fiber; coating said resin coated fiber with monomer of said polymer; polymerizing the monomer coating to form a polymer/resin coated fiber; and aligning the polymer/resin coated fiber and molding same into a desired reinforced thermoplastic composite.
摘要:
Provided are two part hybrid adhesives that comprise an organoborane amine complex, a polyamine, a component polymerizable by free radical polymerization, and a polyisocyanate component. An isocyanate terminated prepolymer can advantageously be used in the practice of the invention. The adhesive is particularly well suited for low surface energy plastic bonding.
摘要:
High performance, low viscosity hot melt adhesives are obtained using acrylic block copolymers. The level of acrylic block copolymer in the adhesive formulation is less than 50% by weight.
摘要:
Thermally shrinkable films or labels having coated thereon a radiation curable adhesive; and a process for applying thermally shrinkable films or labels to containers comprising the steps of a) coating at least a portion of a thermally shrinkable but unshrunken film or label segment with a radiation curable adhesive; b) applying the film or label to the longitudinal surface of the container; c) subjecting the radiation curable adhesive to a radiation source to effect curing thereof and, d) subjecting the container to heat to shrink the film or label onto the container so as to permanently affix it thereto.
摘要:
Hydroxyl-containing ester or acid waxes useful in hot melt adhesives to provide compatible compositions with good thermal stability and color retention are disclosed and have the formula: R(OH).sub.n COOR.sup.1 where R is a hydrocarbon group of 12 to 30 carbons, n is 2 to 6 and R is H, C.sub.1 to C.sub.4 alkyl group or (CH.sub.2 CH.sub.2 O).sub.x H where x is 1 to 4.
摘要:
A nonwoven disposable article is constructed using adhesive compositions containing 1 to 25% of a surfactant, which causes the adhesive composition to exhibit a contact angle of 90.degree. or less and a reduction in surface tension of less than or equal to about 35-40 dynes/cm, giving improved wicking capabilities to the nonwoven.
摘要:
Aqueous, acrylic hair fixative compositions are disclosed which utilize a partially-neutralized acrylic hair fixative polymer. The polymer is neutralized in a solvent system in which water is always the major solvent constituent and organic solvents are optional. Methods of making the hair fixative compositions which require water as the primary solvent utilized to prepare the hair fixative compositions are also disclosed.
摘要:
Novel polyimide and polyisoimide oligomers and precursors thereof, end-capped with diaryl substituted acetylene.These novel end-capped polyimide or polyisoimides oligomers are useful for composites, molding compounds, adhesives, and electronic applications.
摘要:
An ultraviolet (UV) crosslinkable acrylic pressure sensitive adhesive comprises an acrylic copolymer and a cationic photoinitiator. The acrylic copolymer comprises pendant reactive functional groups. The pressure sensitive adhesive formed from the acrylic copolymer with the pendant reactive functional groups result in high green strength and/or high temperature holding strength of the adhesive.
