摘要:
A polymeric composite derived from a reclaimed polymeric material. The polymeric composite in particulate form can be thermally compressed into panels and other embodiments that require a component that possesses sufficient mechanical strength and moisture resistance. In certain embodiments, the panel may be utilized as one layer in a multilayered article.

摘要:
A pavement marking article that has an adhesive composition for adhering the article to a pavement substrate, where the adhesive composition includes a reaction product of an acrylic acid ester of a monohydric alcohol whose homopolymer has a Tg less than 0° C., a non-polar ethylenically unsaturated monomer, and 0-10 parts by weight of a polar ethylenically unsaturated monomer. Preferably the amount of the acrylic acid ester is about 60-90 parts by weight, and the amount of the non-polar ethylenically unsaturated monomer is about 10-40 parts by weight.Also, a raised pavement marker that comprises: (a) a pavement marker body having upper and lower surfaces and an apparent flexural modulus of at least about 50,000 psi and (b) a pressure sensitive adhesive layer disposed upon the lower surface of the marker, wherein the adhesive has: (i) a transition region that begins at a frequency of about 10,000 radians/s or more and extends to a frequency of about 100 radians/s or less at about 25° C.; and (ii) a minimum shear modulus of about 1×105 Pa at an impact frequency of about 100 radians/s at 25° C.; and (iii) a shear modulus value of about 2×104 to 2×105 Pa at a frequency of 1 rad/sec at 25° C. Raised pavement markers that use a pressure sensitive adhesive meeting parameters (i)-(iii) can demonstrate good adhesion to roadways and are capable of withstanding repeated impacts from motor vehicle tires.

Solute polymers in solvent monomers form a coatable syrup that can be cured to a viscoelastomeric material when radiation-sensitive hydrogen abstracting groups in either the polymer or one of the monomers are exposed to ultraviolet radiation. The solute polymers can be formed from the solvent monomers.
