The intense purple dye normally found in purple primers for use in the adhesive bonding of plastics is replaced with a leuco dye capable developing a visually intense color when activated through contact with the particular plastic being bonded or a complementary solvent cement.

Color developing colorless primer

Provided are methods for obtaining modified polyarylene sulfide compositions having improved thermal and thermo-oxidative stability, the compositions so obtained, and articles comprising the compositions. The method comprises the steps of contacting, in the presence of a suitable solvent, a polyarylene sulfide with at least one reducing agent and at least base to form a first mixture. The reducing agent comprises zinc(0), tin(0), tin(II), bismuth (0), bismuth(III), or a combination thereof. The first mixture is heated to form a second mixture in which the polyarylene sulfide is dissolved. The polyarylene sulfide is then precipitated to obtain a modified polyarylene sulfide.

Solution phase processing of polyarylene sulfide

A polymer comprising polycyclic repeating units having recurring ion conducting groups and optional crosslinkable groups is disclosed. The present invention provides the capability of tailoring polymers to impart unique properties to membranes fabricated from the polymers. Membranes comprising the polymers and methods for preparing the membranes and their use in ion conducting membranes, particularly in fuel cells, are also provided.

Polycyclic polymers containing pendant ion conducting moieties

Macrocyclic compounds, e.g., ketones, crown ethers, methicones etc., have been found to be effective co-solvents in solvent based adhesives for pipe joining applications. Because of their enhanced solubility with VOC exempt solvents (40 C.F.R. 51.100), the calculated VOC content of the adhesive can be lowered to at least 75% of those established by SCAQMD Rule 116A.

Plastic adhesive

Oligomers of polycyclic olefin monomers, and optionally allylic or olefinic monomers, and a method of making such oligomers that includes reacting polycyclic olefin monomers in the presence of a Ni or Pd containing catalyst, or in the case of allylic monomers in the presence of a free radical initiator. The oligomers can be included in photoresist compositions as dissolution rate modifiers. The photoresist compositions can further include a polymeric binder resin, a photoacid generator, and solvents.
