Provided is a composition capable of providing a formed article that, even when using continuous fibers, has excellent interfacial adhesion between the continuous fibers and a matrix resin, and as a result, has excellent mechanical strength (e.g., impact resistance and flexural strength). One aspect of a composition according to the present invention includes a polymer (A) including an amino group, fibers (B), and a thermoplastic resin (C), in which a content ratio of the fibers (B) is 70 parts by mass or more and 250 parts by mass or less based on 100 parts by mass of the thermoplastic resin (C). Another aspect of the composition according to the present invention includes a polymer (A) including an amino group, a non-woven fabric (B), and a thermoplastic resin (C).

[Problem] To provide a gel which can be produced in a short time, has controlled properties such as modulus and expansion pressure, and has a low polymer concentration. [Solution] A process for producing a polymer gel in which gel-precursor clusters have been crosslinked with one another to form a three-dimensional network structure, characterized by comprising a) a step in which monomer or polymer units that are present in a concentration less than a critical gelation concentration are crosslinked to form the gel-precursor clusters, the gel-precursor clusters having a storage modulus G and a loss modulus G which satisfy the relationship G<G, and b) a step in which the gel-precursor clusters are crosslinked with one another by a crosslinking agent to obtain a gel having a three-dimensional network structure.

A molded body includes a non-foamed design layer, a foamed intermediate layer, and a non-foamed back layer, laminated in this order and formed of a first, second, and third resin compositions, respectively. The first, second, and third resin compositions contain a polyolefin as a main component. The first resin composition is an impact-resistant resin composition including a polyolefin, a polyamide, and a polyolefin-based modified elastomer having a reactive group reactive with the polyamide. A method of producing the molded body includes disposing a first support layer to serve as the design layer and a third support layer to serve as the back layer so as to be spaced apart from and face each other, interposing the second resin composition provided with foamability in a gap between the first and third support layers, and forming the intermediate layer by expanding the gap while causing the second resin composition to foam.

A method of reducing foamed density that results in a foamed polyvinyl chloride (PVC) component exhibiting reduced density. The foamed PVC component contains at least a PVC resin and a process aid blend. The process aid blend contains from 1 weight % to 60 weight % (based on the weight of the blend) of a functionalized process aid, and from 99 weight % to 40 weight % (based on the weight of the blend) of a non-functionalized process aid. The functionalized process aid includes at least one base polymer functionalized with a reactive epoxy, hydroxyl, -keto ester, -keto amide, or carboxylic acid functional group. The foamed PVC component containing the process aid blend has a lower density than a reference foamed PVC component made using the same process conditions and additives, but which contains only non-functionalized process aid and not the functionalized process aid.
